Illusionist Siegfried Fischbacher, the surviving member of the duo Siegfried & Roy, has died in Las Vegas at age 81. His sister confirmed his death from cancer.

Fischbacher’s long-time show business partner, Roy Horn, died in May of complications from COVID-19 at a Las Vegas hospital. He was 75.

The duo astonished millions with their extraordinary magic tricks until Horn was critically injured in 2003 by one of the act’s famed white tigers.

After Horn’s death, Fischbacher told Germany’s weekly Bild am Sonntag newspaper his best friend would always stay by his side.

For years, Siegfried & Roy was an institution in Las Vegas, where Fischbacher and Horn’s magic and artistry consistently attracted sellout crowds. The pair performed six shows a week, 44 weeks per year.

Horn and Fischbacher, both natives of Germany, first teamed up in 1957 and made their Las Vegas debut a decade later. Siegfried & Roy began performing at the Mirage in 1990.

The pair gained international recognition for helping to save rare white tigers and white lions from extinction. Their $10 million compound was home to dozens of rare animals over the years. The white lions and white tigers were the result of a preservation program that began in the 1980s.
