Wilhelm Von Homburg, also known as Norbert Grupe, was born in Berlin, Germany, and began his career as a wrestler in the 1950s, earning fame in Germany and touring the United States. He later adopted the stage name Prinz Wilhelm Von Homburg and transitioned to boxing in the early 1960s, competing in the light heavyweight and heavyweight classes from 1962 to 1970.
Before turning to acting, Wilhelm made his Hollywood debut on the popular television show "Gunsmoke" as "Otto," with the episode "The Promoter" inspired by his life as a boxer. He then had a recurring role on the TV show "The Wild Wild West."
Wilhelm is perhaps best known for his iconic role as "Vigo the Carpathian" in the hit movie "Ghostbusters II." His extensive filmography includes "Die Hard," "Diggstown," "The Package," "Eye of the Storm," "In the Mouth of Madness," "The Devil's Brigade," "The Wrecking Crew," and "Stroszek."
In 1988, Wilhelm made headlines after a controversial appearance on German television at the Z.D.F. Sport Studio, following remarks made by reporter Rainer Günzler about his boxing career and personal life.
In 2002, German filmmaker Gerd Kroske produced the prize-winning documentary "Der Boxprinz," which chronicled Wilhelm's life.
Wilhelm Von Homburg lived in the beautiful Malibu/Santa Monica Mountains with his dog, Kiss, in his later years. He passed away in March 2004 at the Villa Estate of his close friend in Puerto Vallarta, Mexico, due to complications from prostate cancer.
