Horn was born in Nordenham, Germany, paired with Siegfried Fischbacher to perform magic tricks and stunts with big cats. The pair performed worldwide and then became a staple in Las Vegas from 1990 to 2003, ABC News reported.
The act’s regular schedule of performances ended at The Mirage in 2003, when Horn was attacked onstage by his white Bengal tiger, Mantecore.
The tiger bit into Horn's neck and dragged him off stage, KTNV reported. Horn's spine was severed and caused severe injuries, the television station reported. He was initially unable to move, walk or speak after the attack, KNTV reported.
The pair returned to the Las Vegas stage for a final benefit performance in 2009, ABC News reported. The pair said they raised $14 million for the Cleveland Clinic's Lou Ruvo Center for Brain Health.
