Roy Horn of Siegfried & Roy, has passed away due to COVID-19 at the age of 75.The duo, Siegfried & Roy, are known as legendary magicians who performed at a number of venues for millions of people. Horn died of complications from the coronavirus on Friday in a Las Vegas hospital, according to a statement released by publicist Dave Kirvin.“Today, the world has lost one of the greats of magic, but I have lost my best friend,” Siegfried Fischbacher said in the statement. “From the moment we met, I knew Roy and I, together, would change the world. There could be no Siegfried without Roy, and no Roy without Siegfried.”Roy was injured in October 2003 when a tiger named Montecore attacked him on stage at the Mirage hotel-casino in Las Vegas. He had severe neck injuries, lost a lot of blood and later suffered a stroke. He underwent lengthy rehabilitation, but the attack ended his career.“Roy was a fighter his whole life including during these final days,” Fischbacher said. “I give my heartfelt appreciation to the team of doctors, nurses and staff at Mountain View Hospital who worked heroically against this insidious virus that ultimately took Roy’s life.”In February of 2009 the duo made a comeback for their only and final performance to raise money for the new Cleveland Clinic Lou Ruvo Center for Brain Health in Las Vegas. The brief performance, which included Montecore, became the basis of an episode of the ABC television show “20/20.”The duo managed a successful life since they first teamed up back in 1957. They even signed a lifetime contract with the Mirage in 2001, it was estimated they had performed 5,000 shows at the casino for 10 million fans since 1990 and had grossed more than $1 billion. That came on top of thousands of shows at other venues in earlier years.Funeral services will be private, with an expected public memorial.
