1 00:00:00,000 --> 00:00:05,000 An impressive barrier inspires a flight to freedom. 2 00:00:05,000 --> 00:00:09,000 They're petrified. They think they're gonna die. 3 00:00:09,000 --> 00:00:14,000 A haunting beach with a sinister tale of espionage. 4 00:00:14,000 --> 00:00:18,000 They were threatening American national security. 5 00:00:18,000 --> 00:00:22,000 And a four-legged friend that healed a legend. 6 00:00:22,000 --> 00:00:27,000 There was only one friend who could bring him back from the break of illness and despair. 7 00:00:28,000 --> 00:00:32,000 Sometimes the greatest secrets lie in plain sight. 8 00:00:33,000 --> 00:00:36,000 These are the mysteries of the monument. 9 00:00:44,000 --> 00:00:46,000 Berlin, Germany. 10 00:00:46,000 --> 00:00:52,000 This once industrial city has become a mecca for entertainment and culture. 11 00:00:52,000 --> 00:00:57,000 It boasts more than 50 theaters and 175 museums. 12 00:00:57,000 --> 00:01:05,000 But beyond the walls of these esteemed institutions lies what may be the capital's most intriguing exhibition. 13 00:01:07,000 --> 00:01:12,000 It's between 10 and 12 feet high and it's about a half mile long. 14 00:01:12,000 --> 00:01:18,000 And it has paintings by 118 artists from 21 different countries. 15 00:01:18,000 --> 00:01:21,000 And it's considered an international monument to freedom. 16 00:01:21,000 --> 00:01:25,000 A symbol of liberation born out of oppression. 17 00:01:25,000 --> 00:01:27,000 This is the East Side Gallery. 18 00:01:29,000 --> 00:01:32,000 It is the longest surviving stretch of the Berlin Wall. 19 00:01:33,000 --> 00:01:36,000 And according to journalist Stephanie Jackenthal, 20 00:01:36,000 --> 00:01:41,000 this barrier gave rise to one of history's most daring escapes. 21 00:01:41,000 --> 00:01:46,000 This is the story of two families who risk everything for a flight to freedom. 22 00:01:52,000 --> 00:01:54,000 1978. 23 00:01:54,000 --> 00:01:58,000 The Cold War has left Germany a divided nation. 24 00:01:58,000 --> 00:02:01,000 The West is a free democratic society. 25 00:02:01,000 --> 00:02:07,000 But East Germany, which is under Soviet rule, is an oppressive communist state. 26 00:02:08,000 --> 00:02:12,000 Most citizens living in the East are forbidden to cross into the West. 27 00:02:12,000 --> 00:02:17,000 The East Germans were pretty much stuck behind the iron wall of communism. 28 00:02:18,000 --> 00:02:22,000 But 20 miles east of the border in the town of Posnick. 29 00:02:23,000 --> 00:02:27,000 Two friends fantasize about escaping with their families. 30 00:02:28,000 --> 00:02:34,000 37-year-old electrician Peter Strelzik and 24-year-old handyman Gunter Wetzel. 31 00:02:35,000 --> 00:02:41,000 Peter and Gunter dreamed of a life of freedom, where they could read what they want, say what they want, think what they want. 32 00:02:41,000 --> 00:02:44,000 But it seems such talk is wishful thinking. 33 00:02:45,000 --> 00:02:50,000 Separating the East and West is an 836-mile heavily guarded border. 34 00:02:50,000 --> 00:02:55,000 A crossing so feared that parts have become known as the Death Strip. 35 00:02:57,000 --> 00:03:01,000 In the Death Strip, there are vicious dogs, landmines, there are booby traps, 36 00:03:01,000 --> 00:03:06,000 and the police officers have been instructed to shoot anybody trying to escape on site. 37 00:03:07,000 --> 00:03:09,000 The border seemed insurmountable. 38 00:03:10,000 --> 00:03:15,000 Then one day, something catches Peter and Gunter's eyes that gives them hope. 39 00:03:15,000 --> 00:03:22,000 While flicking through the newspaper, they spot a photo of the International Hot Air Balloon Festival in Albuquerque, New Mexico, 40 00:03:22,000 --> 00:03:25,000 and are suddenly struck by an idea. 41 00:03:27,000 --> 00:03:34,000 So looking at the balloons, they think, well, if it was too dangerous to get across the border by land, maybe they could fly over the border. 42 00:03:35,000 --> 00:03:41,000 Yet to carry out this feat, they must somehow build a hot air balloon from scratch. 43 00:03:41,000 --> 00:03:45,000 Seeing the balloon was the first time they even knew a hot air balloon existed. 44 00:03:45,000 --> 00:03:54,000 Finding materials was going to be very difficult in East Germany, and if they got caught, they could be arrested or worse, killed. 45 00:03:55,000 --> 00:04:01,000 Despite the risks, the pair reads everything they can get their hands on about ballooning, 46 00:04:01,000 --> 00:04:05,000 and soon begins the secret project in their workshop. 47 00:04:07,000 --> 00:04:13,000 To propel the craft, they install four propane tanks in a makeshift basket 48 00:04:13,000 --> 00:04:18,000 and convert an old motorcycle engine into a homemade burner. 49 00:04:18,000 --> 00:04:26,000 For the canopy, they stitch together curtains, bedsheets, and any other scrap of cloth they can find. 50 00:04:27,000 --> 00:04:34,000 After months of work, Peter and Gunter complete their giant patchwork balloon. 51 00:04:35,000 --> 00:04:45,000 By the time they're done, they've used 13,000 square feet of fabric, and the balloon itself weighs 400 pounds. 52 00:04:48,000 --> 00:04:51,000 September 16, 1979. 53 00:04:52,000 --> 00:04:59,000 After several test flights in the woods, it's finally time for Peter, Gunter, and their families to make their escape. 54 00:05:00,000 --> 00:05:05,000 In a desolate field 20 miles east of the border, they prepare for takeoff. 55 00:05:06,000 --> 00:05:13,000 They load into the basket, and then they start the burner, and the balloon, much to their delight, fills with air. 56 00:05:14,000 --> 00:05:18,000 Their spirits soar as they make their ascent and head west. 57 00:05:18,000 --> 00:05:22,000 It can see freedom within their reach. 58 00:05:22,000 --> 00:05:26,000 But the most dangerous part of their journey is just ahead. 59 00:05:28,000 --> 00:05:31,000 Suddenly in the sky they see searchlights. 60 00:05:32,000 --> 00:05:35,000 They are approaching the dreaded Death Strip. 61 00:05:37,000 --> 00:05:42,000 And as the beams scan the night sky, disaster strikes. 62 00:05:43,000 --> 00:05:48,000 The burner runs out of gas, and they start to plummet to the ground. 63 00:05:49,000 --> 00:05:54,000 The balloon has just enough hot air left to cushion their crash landing. 64 00:06:00,000 --> 00:06:01,000 We made it. 65 00:06:02,000 --> 00:06:06,000 It was pitch black when they landed. They had no idea where they were. 66 00:06:06,000 --> 00:06:10,000 Then it seems the refugees' worst fears are realized. 67 00:06:10,000 --> 00:06:16,000 They see two men in uniform approaching them, and they're sure that it's the police on the east German side. 68 00:06:18,000 --> 00:06:20,000 They're petrified. They think they're gonna die. 69 00:06:21,000 --> 00:06:26,000 But as the men draw near, it becomes clear the families are mistaken. 70 00:06:26,000 --> 00:06:30,000 Peter and Gunter realize that the officers are wearing West German uniforms. 71 00:06:32,000 --> 00:06:34,000 They're safe. They've made it to freedom. 72 00:06:35,000 --> 00:06:40,000 And the fledgling balloonists have come prepared for the momentous event. 73 00:06:40,000 --> 00:06:46,000 During their research, Peter and Gunter read that balloonists bring champagne to celebrate their landings. 74 00:06:46,000 --> 00:06:50,000 So they popped the cork and toast it to their success. 75 00:06:54,000 --> 00:06:58,000 The two families soon settle into their newfound liberty in the west. 76 00:06:59,000 --> 00:07:06,000 Eventually, in November of 1989, the Berlin Wall is torn down, a powerful sign that the iron communist grip has crumbled. 77 00:07:10,000 --> 00:07:18,000 Today, this monumental fragment survives as a reminder of Germany's days as a divided nation, and the brave souls who rose up in their quest for freedom. 78 00:07:18,000 --> 00:07:22,000 Los Angeles, the motion picture capital of the world. 79 00:07:22,000 --> 00:07:29,000 On any given day, the city of angels hosts nearly a hundred TV and feature film crews. 80 00:07:30,000 --> 00:07:36,000 And at the center of this movie mad metropolis are a set of symbols that are a symbol of the world. 81 00:07:36,000 --> 00:07:38,000 The world is a symbol of the world. 82 00:07:38,000 --> 00:07:40,000 The world is a symbol of the world. 83 00:07:40,000 --> 00:07:42,000 The world is a symbol of the world. 84 00:07:43,000 --> 00:07:51,000 And at the center of this movie mad metropolis are a set of symbols that harkens back to Tinseltown's earliest days. 85 00:07:51,000 --> 00:08:00,000 They have star-shaped hand outlined in brass, and there's several thousand along the intersection of Hollywood and Vine in Los Angeles. 86 00:08:02,000 --> 00:08:11,000 This is the Hollywood Walk of Fame, a 15-block celebration of the most iconic figures in the history of entertainment. 87 00:08:13,000 --> 00:08:21,000 But according to author Kelly Brown, there is one name here that, although lesser known, may be the most important of them all. 88 00:08:21,000 --> 00:08:23,000 Carl Lemley. 89 00:08:24,000 --> 00:08:28,000 This star represents a man who created the star system as we know it today. 90 00:08:29,000 --> 00:08:35,000 What role did this man play in creating the Hollywood that we know and love? 91 00:08:36,000 --> 00:08:41,000 1909. Los Angeles. 92 00:08:42,000 --> 00:08:44,000 It's the golden age of silent movies. 93 00:08:45,000 --> 00:08:48,000 More and more people are flocking to cinemas across America. 94 00:08:49,000 --> 00:08:54,000 To keep audiences happy, studios are racing to produce new films. 95 00:08:55,000 --> 00:09:00,000 To keep up with the demand of the film going public, studios were putting out several reels a week. 96 00:09:01,000 --> 00:09:08,000 With the production of so many features, actors are seen as interchangeable and aren't listed in the credits. 97 00:09:09,000 --> 00:09:12,000 Audiences aren't even aware of their names. 98 00:09:14,000 --> 00:09:17,000 Nevertheless, one actress catches the public's eye. 99 00:09:18,000 --> 00:09:22,000 This one blonde stood out. She was a very, very talented actress. 100 00:09:22,000 --> 00:09:27,000 Each week she played a different role, and each week the public just fell in love with her more and more. 101 00:09:28,000 --> 00:09:36,000 Since the public doesn't know the enigmatic actress's real name, her fans create one of their own after the studio she works for. 102 00:09:37,000 --> 00:09:38,000 Biograph films. 103 00:09:39,000 --> 00:09:43,000 The people didn't have any other way of identifying her, so they began calling her the Biograph Girl. 104 00:09:44,000 --> 00:09:50,000 Yet the popular performer's spectacular rise will soon come to an abrupt halt. 105 00:09:51,000 --> 00:09:58,000 On the morning of February 19, 1910, the public wakes to reports that the Biograph Girl is dead. 106 00:10:00,000 --> 00:10:03,000 There were reports in the press that Florence was been killed in a streetcar accident. 107 00:10:05,000 --> 00:10:10,000 And in the wake of the tragedy, fans finally learn the identity of their fallen favorite. 108 00:10:11,000 --> 00:10:13,000 Her name is Florence Lawrence, and she's 26 years old. 109 00:10:14,000 --> 00:10:17,000 The actress's followers are devastated. For weeks they mourn her untimely death. 110 00:10:18,000 --> 00:10:21,000 But then, on March 12th, the tragic tale takes a bizarre turn. 111 00:10:23,000 --> 00:10:30,000 A full-page advertisement appears in a popular newspaper, and it features a familiar face. 112 00:10:31,000 --> 00:10:37,000 This advertising said Florence Lawrence was alive and was going to appear in a new film with the Independent Moving Picture Company. 113 00:10:38,000 --> 00:10:44,000 It seems Florence Lawrence, aka the Biograph Girl, has somehow come back from the dead. 114 00:11:01,000 --> 00:11:02,000 It's February 1910. 115 00:11:03,000 --> 00:11:11,000 Fans of silent film are devastated when they learn that their favorite actress, Florence Lawrence, has died in a car crash. 116 00:11:12,000 --> 00:11:19,000 But weeks later, an advertisement appears announcing that she's not dead after all, and will even star in a new movie. 117 00:11:20,000 --> 00:11:23,000 So what really happened to this enigmatic actress? 118 00:11:24,000 --> 00:11:31,000 This advertisement created a sensation, both in public and the trade press. 119 00:11:32,000 --> 00:11:36,000 People wanted proof that Florence was still alive. 120 00:11:39,000 --> 00:11:48,000 But sure enough, on March 25th, at a screening for her new movie, The Broken Oath, Florence Lawrence makes a personal appearance. 121 00:11:48,000 --> 00:11:52,000 It's an unprecedented moment in the history of film. 122 00:11:53,000 --> 00:11:57,000 When Florence arrived in St. Louis, she is greeted by a mob of people. 123 00:11:58,000 --> 00:12:04,000 For a film actress to make their personal appearance was unheard of. It had never been done before. 124 00:12:08,000 --> 00:12:11,000 Lawrence achieves a level of fame the industry has never seen. 125 00:12:11,000 --> 00:12:16,000 Her name and face are plastered over billboards, wherever The Broken Oath plays. 126 00:12:17,000 --> 00:12:20,000 The world's first movie star is born. 127 00:12:21,000 --> 00:12:26,000 All a theater owner had to do was put the name Florence Lawrence and people would come to see her. 128 00:12:30,000 --> 00:12:36,000 So what's the truth behind the bizarre tales of Florence Lawrence's death and unexpected reappearance? 129 00:12:41,000 --> 00:12:46,000 The answer lies with the founder of the independent movie pictures company, Carl Lemley. 130 00:12:48,000 --> 00:12:52,000 It turns out this was all part of a fantastic publicity stunt. 131 00:12:53,000 --> 00:13:00,000 With the independent movie pictures company in its infancy, Lemley needed a way to boost ticket sales. 132 00:13:01,000 --> 00:13:06,000 So he secretly wooed Florence Lawrence away from her longtime studio, Biograph Films. 133 00:13:06,000 --> 00:13:11,000 You are going to be big, big star people. 134 00:13:12,000 --> 00:13:16,000 Yet rather than simply releasing a statement about the actress's move to his company, 135 00:13:17,000 --> 00:13:20,000 Lemley decided to make an even bigger splash. 136 00:13:22,000 --> 00:13:26,000 He planted the news of the Biograph Girls death in the papers, 137 00:13:27,000 --> 00:13:32,000 betting that when they identified her as Florence Lawrence, it would make her a household name. 138 00:13:32,000 --> 00:13:38,000 We used the story of her death to connect the public with her name and she became the first movie star. 139 00:13:41,000 --> 00:13:47,000 From that moment on, other studios began promoting their performers to boost ticket sales. 140 00:13:49,000 --> 00:13:56,000 This changed film history. Everything that we know about Hollywood today, red carpets and photographers and film premieres, 141 00:13:57,000 --> 00:13:59,000 we can date back to this publicity stunt. 142 00:13:59,000 --> 00:14:04,000 Carl Lemley achieves his own success by forming Universal Pictures. 143 00:14:06,000 --> 00:14:11,000 And in 1960, Lemley is immortalized on the Hollywood Walk of Fame, 144 00:14:12,000 --> 00:14:18,000 a fitting tribute to the visionary who behind the scenes became one of Tinseltown's brightest stars. 145 00:14:19,000 --> 00:14:22,000 The rugged beauty of Bar Harbor, Maine, 146 00:14:23,000 --> 00:14:28,000 found its fame as a summer haven for the rich and famous at the turn of the 20th century. 147 00:14:29,000 --> 00:14:35,000 Today, the town's fresh lobster and scenic views still draw in 2 million visitors each year. 148 00:14:38,000 --> 00:14:43,000 But just across the bay lies a jagged headland where few tourists dare to tread. 149 00:14:43,000 --> 00:14:48,000 It's a small pebbly beach, raw rocks, greasy, lot of wind, 150 00:14:49,000 --> 00:14:53,000 and it's a place you would go to do something that you didn't want others to see. 151 00:14:54,000 --> 00:14:59,000 This is Hancock Point and as history professor, Herb Adams reveals, 152 00:15:01,000 --> 00:15:07,000 this secluded strip of land was once the gateway to a sinister plan to cripple the United States. 153 00:15:07,000 --> 00:15:12,000 These people are bent on the destruction of the country. 154 00:15:12,000 --> 00:15:17,000 They were threatening the very fabric of American national security. 155 00:15:27,000 --> 00:15:30,000 November 29, 1944. 156 00:15:31,000 --> 00:15:34,000 World War II is in its sixth brutal year 157 00:15:34,000 --> 00:15:37,000 and the Allies are closing in on Germany. 158 00:15:38,000 --> 00:15:43,000 But just off the coast of Maine, a plot is unfolding that the Nazis believe 159 00:15:43,000 --> 00:15:46,000 will turn the tide back in their favor. 160 00:15:48,000 --> 00:15:57,000 Just a few days after Thanksgiving, a large 250-foot-long U-boat quietly approaches Hancock Point. 161 00:15:58,000 --> 00:16:01,000 Soon afterward, a dinghy splashes ashore. 162 00:16:01,000 --> 00:16:04,000 And its two passengers step onto the beach. 163 00:16:05,000 --> 00:16:11,000 These two well-dressed men carrying a heavy suitcase have been sent up to infiltrate the United States 164 00:16:11,000 --> 00:16:14,000 as war effort and its society. 165 00:16:16,000 --> 00:16:19,000 The dapper pair are Nazi spies. 166 00:16:20,000 --> 00:16:26,000 The ranking officer is a highly trained 24-year-old German agent named Eric Gimpel. 167 00:16:26,000 --> 00:16:32,000 His assistant is 26-year-old William Kolpa, a decidedly unlikely spy. 168 00:16:33,000 --> 00:16:37,000 Kolpa is an American from Connecticut. 169 00:16:37,000 --> 00:16:42,000 Kolpa actually served in the United States Naval Reserve at one point. 170 00:16:42,000 --> 00:16:45,000 Kolpa is a defector. 171 00:16:46,000 --> 00:16:52,000 The spies will connect with Nazi informants with the goal of destroying America's top secret weapon. 172 00:16:52,000 --> 00:16:54,000 The Atomic Bomb. 173 00:16:55,000 --> 00:17:02,000 The Manhattan Project. The Atomic Bomb is within seven months of becoming reality at that point in time. 174 00:17:03,000 --> 00:17:09,000 If Kolpa and Gimpel are successful, it would cripple the war effort in the United States. 175 00:17:09,000 --> 00:17:15,000 The spies have been given a suitcase with $60,000 in cash to fund their mission. 176 00:17:16,000 --> 00:17:21,000 They travel to the hub of the United States Naval Reserve. 177 00:17:22,000 --> 00:17:26,000 The Atomic Bomb's research facilities. Manhattan, New York. 178 00:17:26,000 --> 00:17:31,000 There, the pair books a room in an unassuming hotel and gets to work. 179 00:17:33,000 --> 00:17:37,000 Gimpel is hardcore. He's mission-oriented. 180 00:17:38,000 --> 00:17:45,000 Kolpa is neither of those things, and there's a good deal of tension between the defector and the master spy. 181 00:17:45,000 --> 00:17:51,000 But, odd couple as they are, both of them are bent upon the destruction of the United States. 182 00:17:52,000 --> 00:18:00,000 Over the next few weeks, Gimpel and Kolpa begin seeking out information on the Manhattan Project's sites they hope to wipe out. 183 00:18:01,000 --> 00:18:07,000 They connect with known German contacts in New York City to gather what intelligence they can. 184 00:18:08,000 --> 00:18:17,000 There are assembling radio parts that would send this information back to German submarines off the coast of the United States. 185 00:18:18,000 --> 00:18:21,000 Everything is going pretty much according to plan. 186 00:18:24,000 --> 00:18:28,000 But on December 21st, their devilish plot starts to unravel. 187 00:18:29,000 --> 00:18:34,000 Gimpel comes home one day and finds Kolpa. Isn't there? 188 00:18:35,000 --> 00:18:39,000 The young American has vanished, along with all their money. 189 00:18:40,000 --> 00:18:44,000 The $60,000 is missing. 190 00:18:45,000 --> 00:18:49,000 Gimpel begins to worry immediately about what this means. 191 00:18:50,000 --> 00:18:55,000 So where has Kolpa gone? And what has he done with the cash? 192 00:19:00,000 --> 00:19:02,000 It's December 1944. 193 00:19:03,000 --> 00:19:10,000 World War II is raging, and an unlikely pair of Nazi spies have infiltrated New York City. 194 00:19:10,000 --> 00:19:16,000 They are Eric Gimpel, a German spy master, and William Kolpa, a US-born trader. 195 00:19:17,000 --> 00:19:21,000 Their goal is to infiltrate America's top secret atomic bomb program. 196 00:19:22,000 --> 00:19:27,000 But just days into their mission, Kolpa disappears, leaving Gimpel in a panic. 197 00:19:30,000 --> 00:19:35,000 Over the next week, Gimpel lays low, hoping Kolpa will return. 198 00:19:36,000 --> 00:19:40,000 But on December 31st, his worst fears are realized. 199 00:19:41,000 --> 00:19:45,000 While out buying a newspaper, he is arrested by the FBI. 200 00:19:46,000 --> 00:19:49,000 It seems his partner has confessed to the police. 201 00:19:50,000 --> 00:19:55,000 Gimpel, he's been betrayed by Kolpa, betrayed by the American defector. 202 00:19:57,000 --> 00:20:03,000 It turns out when Kolpa was left alone with the suitcase packed with cash, he just couldn't help himself. 203 00:20:06,000 --> 00:20:10,000 He ditched his co-or and ran away with a 60 grand. 204 00:20:13,000 --> 00:20:21,000 He goes to shows. He enjoys good wine. He takes out fancy women. He's having a very fine time. 205 00:20:22,000 --> 00:20:25,000 But Kolpa knew the funds would eventually run out. 206 00:20:27,000 --> 00:20:34,000 So he turned himself into police, hoping to trade information on Gimpel for his own immunity. 207 00:20:35,000 --> 00:20:38,000 But the authorities were in no mood to negotiate. 208 00:20:39,000 --> 00:20:48,000 In February of 1945, Eric Gimpel and William Kolpa are imprisoned for their acts of espionage. 209 00:20:49,000 --> 00:20:55,000 They are the last two Nazi spies to be tried before a military tribunal in the United States. 210 00:20:56,000 --> 00:20:57,000 And all of world were too. 211 00:20:59,000 --> 00:21:04,000 But if they were never caught, they could have been an absolute catastrophe. 212 00:21:06,000 --> 00:21:16,000 Today, the beach at Maine's Hancock Point, known as the Nazi spy landing site, is a stark reminder of a dastardly plot foiled only by greed. 213 00:21:23,000 --> 00:21:29,000 The city of Worcester, Massachusetts boasts a reputation as a thriving academic hub. 214 00:21:30,000 --> 00:21:36,000 It is home to ten colleges and universities that have fostered some of the nation's brightest minds. 215 00:21:39,000 --> 00:21:45,000 And on the campus of Clark University is a tribute to one of the greatest thinkers of the 20th century. 216 00:21:47,000 --> 00:21:54,000 It is six feet tall. It's made out of bronze. It shows late middle age. 217 00:21:54,000 --> 00:22:05,000 Man, he's dressed formally. He looks thoughtful, concerned, and is someone who has restructured the way we think about human nature. 218 00:22:06,000 --> 00:22:12,000 This is Sigmund Freud. The Austrian neurologist is considered the father of psychotherapy. 219 00:22:13,000 --> 00:22:21,000 But as Professor Robert Tobin can attest, some believe that in the last years of his life, Freud had gone to the dogs. 220 00:22:22,000 --> 00:22:30,000 This is the story of a brilliant genius who fell into hard times, and there was only one friend who could bring him back from the break of illness and despair. 221 00:22:31,000 --> 00:22:37,000 How did Freud's unique friendship give rise to a life-changing phenomenon that helped heal the world? 222 00:22:40,000 --> 00:22:43,000 The early 1920s, Vienna, Austria. 223 00:22:44,000 --> 00:22:52,000 Over the previous three decades, 67-year-old Dr. Sigmund Freud has established himself as the world's foremost psychoanalyst. 224 00:22:54,000 --> 00:23:01,000 Sigmund Freud was one of the greatest thinkers of the modern world, along with Marx, Darwin, and Einstein. 225 00:23:02,000 --> 00:23:10,000 He has made psychoanalysis a respected discipline that is taken seriously at universities and in medical institutions throughout the world. 226 00:23:11,000 --> 00:23:18,000 Considered to be at the peak of his career, the public is clamoring to see what he'll achieve next. 227 00:23:19,000 --> 00:23:28,000 He was very focused on his research and what he believed was actually going to change the way humanity might conduct itself in the future. 228 00:23:29,000 --> 00:23:36,000 And he had probably six patients a day, as well as giving lectures. So it's a very full schedule. 229 00:23:37,000 --> 00:23:42,000 But in February of 1923, his busy career is stopped in his tracks. 230 00:23:45,000 --> 00:23:51,000 After years of smoking 20 cigars a day, Freud discovers he is suffering from jaw cancer. 231 00:23:53,000 --> 00:24:00,000 I think he was concerned about his livelihood, about his career, and about his research. 232 00:24:01,000 --> 00:24:07,000 To eradicate the tumor, the Austrians doctors are forced to remove a large portion of his jaw. 233 00:24:08,000 --> 00:24:15,000 But while the surgeries successfully control the disease, Freud is left suffering debilitating pain. 234 00:24:17,000 --> 00:24:26,000 Freud had to give up lecturing at the university. He also, at one point, says that he's gone four weeks without an idea. 235 00:24:26,000 --> 00:24:31,000 And this is the first time that it's been so long that cancer really did wipe him out. 236 00:24:33,000 --> 00:24:40,000 Sigmund Freud faces the grim possibility that his days as a psychoanalyst are about to come to an end. 237 00:24:41,000 --> 00:24:45,000 Imagine being in the prime of your career and having all of that thrown into jeopardy. 238 00:24:46,000 --> 00:24:52,000 But the answer to his problem is about to come in the form of an unlikely and oddly furry savior. 239 00:24:57,000 --> 00:25:04,000 It's 1930 in Vienna. When the founding father of psychoanalysis, Sigmund Freud, is struck down by jaw cancer, 240 00:25:05,000 --> 00:25:14,000 his pioneering research grinds to a halt. But little does he know an unlikely source of creature comfort maybe just around the corner. 241 00:25:16,000 --> 00:25:20,000 Depressed and enfeebled, Freud searches for a way to lift his spirits. 242 00:25:21,000 --> 00:25:29,000 Then, at his daughter's suggestion, he welcomes a new addition to his family. One of the four-legged variety. 243 00:25:30,000 --> 00:25:40,000 Freud receives a chow-chow, this somewhat roundish dog with a lot of fur and a big smile on its face, named Yofi. 244 00:25:41,000 --> 00:25:49,000 Freud instantly connects with Yofi. The dog's company helps to take his mind off his pain and get him through his busy schedule. 245 00:25:50,000 --> 00:26:00,000 Yofi's presence really did cheer Freud up. I think Freud found that he had someone that was less complicated than most of his patients, 246 00:26:01,000 --> 00:26:03,000 and that was also understanding of his own difficulties. 247 00:26:05,000 --> 00:26:11,000 Soon, the two are inseparable. Yofi even sits in on Freud's therapy sessions. 248 00:26:13,000 --> 00:26:18,000 And it's here that the psychoanalyst notices a change in his patient's behavior. 249 00:26:20,000 --> 00:26:27,000 Remarkably, when the dog is present, they seem more willing to divulge details of their painful experiences. 250 00:26:28,000 --> 00:26:37,000 Yofi could absorb some of the trauma, could absorb some of the stress, could also make the whole therapy session feel a little bit more informal. 251 00:26:38,000 --> 00:26:42,000 It's really amazing that Yofi made these therapeutic sessions more effective. 252 00:26:43,000 --> 00:26:52,000 Freud marvels at this phenomenon and starts noting in his diaries the positive effect that dogs may have on the human psyche. 253 00:26:53,000 --> 00:27:02,000 And so Freud seems to have been the first to hypothesize about the ability of the dog to empathize and to understand what was going on with the human being. 254 00:27:04,000 --> 00:27:11,000 Sadly, the distinguished doctor passes away before he can fully study the psychological benefits of Canaan companions. 255 00:27:13,000 --> 00:27:19,000 But in the 1960s, a group of psychologists rediscover Freud's observations. 256 00:27:20,000 --> 00:27:27,000 They soon introduce his ideas to mainstream medicine, and the concept of therapy dogs is born. 257 00:27:28,000 --> 00:27:35,000 Today, an estimated 200,000 of our four-legged friends are helping to heal patients in the United States. 258 00:27:36,000 --> 00:27:40,000 And I think we can say Yofi was the first therapy dog. 259 00:27:41,000 --> 00:27:54,000 And this statue on the campus of Clark University stands as a memorial to the brilliant thinker who discovered that during the darkest of times, a dog may truly be a man's best friend. 260 00:27:58,000 --> 00:28:04,000 San Antonio, Texas. More tourists visit this city than any other in the Lone Star State. 261 00:28:05,000 --> 00:28:10,000 Thanks to its mild weather, family-friendly museums, and cafe-lined river walk. 262 00:28:13,000 --> 00:28:20,000 But there's one attraction in town that, despite its popularity, was never designed to draw in the crowds. 263 00:28:21,000 --> 00:28:26,000 It's about three acres of land. It has these limestone walls about three feet thick. 264 00:28:27,000 --> 00:28:34,000 And it's really a marvel of architecture and a place that has enormous historical significance. 265 00:28:35,000 --> 00:28:36,000 This is the Alamo. 266 00:28:39,000 --> 00:28:47,000 Built as a Franciscan mission, the structure is now remembered as a fort that survived a famous 1836 siege. 267 00:28:48,000 --> 00:28:57,000 But as author Andrew Carroll knows, this beloved historic site would look very different were it not for an unlikely heroine. 268 00:28:58,000 --> 00:29:01,000 You had what became known as the second battle for the Alamo. 269 00:29:05,000 --> 00:29:07,000 San Antonio, 1905. 270 00:29:08,000 --> 00:29:15,000 44-year-old schoolteacher Adina Dezevala has just been appointed as a custodian of the legendary Alamo. 271 00:29:16,000 --> 00:29:19,000 For her, the compound holds a deep significance. 272 00:29:20,000 --> 00:29:24,000 Adina was the daughter of the first vice president of the Republic of Texas. 273 00:29:25,000 --> 00:29:28,000 So she had a real passion for saving Texas history. 274 00:29:29,000 --> 00:29:34,000 As a caretaker of the hallowed site, Adina has her work cut out for her. 275 00:29:34,000 --> 00:29:42,000 This beautiful building had fallen into total disrepair. There was graffiti, it had been vandalized, and people had been chipping away at the statues. 276 00:29:44,000 --> 00:29:48,000 But for the schoolteacher, the site deserves to be lovingly preserved. 277 00:29:49,000 --> 00:29:53,000 In particular, a critical part of the building known as the Long Barracks. 278 00:29:54,000 --> 00:30:00,000 The Long Barracks were many of the defenders had died, but it was also one of the oldest parts of the whole compound. 279 00:30:00,000 --> 00:30:08,000 And so she envisioned that it would become a museum or a library that would teach people about the history of the battle and the Alamo itself. 280 00:30:09,000 --> 00:30:14,000 But there's a problem. Adina's authority as caretaker is shared with another woman. 281 00:30:15,000 --> 00:30:18,000 22-year-old ranching heiress Clara Driscoll. 282 00:30:19,000 --> 00:30:23,000 And Clara's vision for the Alamo's preservation is very different. 283 00:30:24,000 --> 00:30:31,000 To Clara, the Long Barracks were an eyesore and she wanted to see them knocked down and put up hotels and other tourist attractions. 284 00:30:33,000 --> 00:30:42,000 Adina is outraged by Clara's disregard for the history of the Alamo and vows to protect the Long Barracks at all cost. 285 00:30:43,000 --> 00:30:52,000 And over the next three years, the custodians squabble in court over how to best preserve the building, leaving the fate of the Alamo in limbo. 286 00:30:54,000 --> 00:31:04,000 But then in 1908, Adina receives some disturbing news. Clara has disregarded the courts and gone behind her back. 287 00:31:05,000 --> 00:31:11,000 Adina hears that Clara is going to rent out the Long Barracks to a group of vaudeville performers. 288 00:31:11,000 --> 00:31:24,000 Adina knows that possession is nine-tenths of the law. She fears that once Clara and her performers occupy the Barracks, her rival will be just one step away from raising them to the ground. 289 00:31:25,000 --> 00:31:30,000 Desperate to secure the fate of the priceless relic, Adina takes drastic action. 290 00:31:31,000 --> 00:31:36,000 She hires armed guards to stand outside the Long Barracks to prevent the new tenants from coming in. 291 00:31:36,000 --> 00:31:53,000 The San Antonio Sheriff quickly catches wind of her plan. Though no court has declared Clara the rightful custodian, he sides with the young heiress and orders Adina's guards off the Alamo grounds. 292 00:31:56,000 --> 00:31:59,000 But Adina isn't giving up that easily. 293 00:32:00,000 --> 00:32:02,000 And this is when the real standoff begins. 294 00:32:07,000 --> 00:32:18,000 It's February 1908, San Antonio, Texas. Alamo caretaker, Adina Dezavala, reveres the compound as sacred ground. 295 00:32:19,000 --> 00:32:29,000 So when she hears that her fellow caretaker and rival, Clara Driscoll, is scheming to destroy part of the site, she decides to make her own last stand. 296 00:32:30,000 --> 00:32:38,000 As the sheriff ushers her hired guards off the Alamo grounds, Adina springs into action. 297 00:32:41,000 --> 00:32:45,000 She slams the door, locks it, and barricades herself inside. 298 00:32:49,000 --> 00:32:53,000 The middle-aged schoolteacher has decided to try and hold the fort on her own. 299 00:32:54,000 --> 00:33:00,000 She declares that unless the building's preservation is assured, she will not leave. 300 00:33:01,000 --> 00:33:04,000 Adina was ready for a long siege if that's what it would come to. 301 00:33:05,000 --> 00:33:14,000 The sheriff could send in his men to drag her out, but with a curious crowd gathering, he opts for a different tactic to ferret out his agitator. 302 00:33:15,000 --> 00:33:22,000 He cuts off the electricity and he refuses anyone from going in or out of the building to bring her food or water, any kind of supplies. 303 00:33:23,000 --> 00:33:28,000 Adina spends a frigid night inside the dark, rat-infested barracks. 304 00:33:32,000 --> 00:33:36,000 By morning, it's clear the sheriff believes the holdout is about to end. 305 00:33:37,000 --> 00:33:39,000 But Adina stands firm. 306 00:33:40,000 --> 00:33:43,000 And soon, she won't be alone in her battle.
