He trained to walk on a high wire, cycle across a tightrope, and balance as one of a seven-man pyramid. For him, it seemed, nothing was impossible.Then, on March 22, 1978, the world watched in horror as Karl Wallenda fell to his death. As he attempted to walk across a high wire strung between the two towers of the Condado Plaza Hotel in San Juan, Puerto Rico, the 73-year-old Wallenda lost his balance, teetering on the wire for 30 heart-stopping seconds before plummeting 10 stories.This is the full story of Karl Wallenda, from his astonishing feats to his tragic death.How Karl Wallenda Became A Legendary Tightrope Walker And All-Around Daredevil PerformerState Library and Archives of FloridaThe Flying Wallendas perform their famous pyramid act in the 1960s.Karl Wallendas ancestors started performing as a traveling circus troupe in the streets and cafes of Germany as far back as 1780. The family consisted of acrobats, jugglers, clowns, aerialists, and animal trainers. They took their act through small towns and villages across Europe, performing in public squares and wherever else they could gather a crowd. They mostly relied on donations from their audiences in order to keep the troupe going.Karl Wallenda was born into this circus family in Magdeburg, Germany in 1905. He started performing with his family at just six years old, and leveled up to doing stunts in beer halls by the time he was only 11. Wallendas most impressive stunt at that age was stacking chairs and then doing a handstand on top of them.After more years of training with his family, Wallenda answered an ad to support the wire-walker Louis Weitzmanns circus troupe with their tightrope walking acts. Wallendas main job there was to walk out behind Weitzmann onto the wire and perform a handstand on his feet as Weitzmann laid down.That experience propelled Karl Wallenda to create his own act in 1922, enlisting his brother Herman, girlfriend Helen Kreiss (who eventually became his wife), and school friend Joseph Geiger, all of whom had circus training.Known as The Great Wallendas, the group toured Europe for several years, performing tightrope walking and high-wire bicycling, and perfecting a four-man pyramid act.Eventually, they were noticed by American circus entrepreneur John Ringling during their act in Cuba, and he immediately hired the Wallendas to perform at the Ringling Bros. and Barnum & Bailey Circus. In 1928, they debuted to a 15-minute standing ovation at New Yorks Madison Square Garden. The group remained Ringling headliners for much of the next two decades.The Wallenda FamilyThe Flying Wallendas peform at the Circo Zoppe.After all four members fell during a wire slip at a show in Akron, Ohio in 1962, a reporter dubbed the group The Flying Wallendas because of how gracefully the members fell they looked, he thought, like they were flying.The Flying Wallendas soon gained international fame for their impressive acts, which were developed almost entirely by Karl Wallenda. One of the most death-defying stunts he came up with was the three-tier, seven-person chair pyramid, in which the group walked the tightrope with the top member balancing high above in the air, often on a chair.As the acts fame continued to grow, so too did Karl Wallendas family, as he had gotten married and had several children along the way. All of them eventually joined the family business, along with their respective significant others and their own children. As the middle of the 20th century came and went, the Flying Wallendas were only getting bigger in every sense of the word.When The Flying Wallendas Daredevil Stunts Turned DeadlyWhen successful, the acts created and popularized by the Wallenda family were astounding.

Wallendas son Mario was paralyzed from the waist down, and his niece sustained a head injury after bouncing out of the safety net.

Wallenda walked Busch, Veterans, JFK, and 3 Rivers Stadiums, as well as the Astrodome, among many others.Wallenda made history several times, performing a 700-foot high-wire walk and handstanding across Georgias Tallulah Gorge in front of an audience of 30,000 people, and also breaking a world high-wire record by walking 1,800 feet across Kings Island near Cincinnati, Ohio.Georgia State ParksKarl Wallenda walking across Tallulah Gorge in 1970.He performed stunts into his 70s, taking on every challenge with the same excitement hed had all his life.The Final Walk: Karl Wallendas Death And The Legacy He Left BehindWith a career that spanned more than half a century, Wallenda was far from retiring when he headed to San Juan, Puerto Rico in 1978.

He holds 11 Guinness World Records, including performing the longest and highest bicycle ride (at 250-feet long and 135-feet high), and the highest tightrope walk while blindfolded.In 2011, Nik, alongside his mother Delilah, recreated the same walk that had led to Karl Wallendas demise some 33 years prior. The duo walked a tightrope between the two towers of the 10-story Condado Plaza Hotel in Puerto Rico.Nik claimed he wasnt scared during the performance, but was instead honored to be able to conquer this once-deadly challenge: To be able to walk in his exact footsteps is an extremely huge honor, and I did this for him as much as I did it for my family to get some closure too.Everything about Karl Wallendas astonishing life and career surely makes it seem as though he would have been proud of his great-grandsons historic achievement.After this look at Karl Wallenda, read about daredevil Wu Yongning, who eventually died during a stunt.
