About Janos Prohaska

Lived 1919 – 1974 (aged 54). Janos Prohaska was a Hungarian and American actor, film actor, stunt performer and television actor.

Janos Prohaska (born János Prohászka; October 10, 1919 – March 13, 1974) was a Hungarian-born American actor and stunt performer. He appeared on American television from the 1960s and usually played the roles of animals (mostly bears and gorillas) or monsters.

He played a recurring comic role as The Cookie Bear on The Andy Williams Show from 1969 to 1971. Prohaska also appeared in multiple roles on TV series including The Outer Limits, Bewitched, I Dream of Jeannie, Lost in Space, and a few episodes of Gilligan's Island, where he plays a gorilla. His only credited role on that series appears in the episode "Our Vines Have Tender Apes." He also played the title role in the 1965 Perry Mason episode, "The Case of the Grinning Gorilla". In 1967 he appeared as a white gorilla in the "Fatal Cargo" episode of the ABC-TV sci-fi series Voyage to the Bottom of the Sea.

He was in the first Star Trek pilot, The Cage, as an ape and as a humanoid bird. Later he was in three episodes of the original Star Trek series, wearing alien costumes he himself designed and made as the Horta in "The Devil in the Dark" and the mugato in "A Private Little War".

He also stunt-doubled for both Arnold Stang and Peter Falk in the 1963 film It's a Mad, Mad, Mad, Mad World in which Stang, a small and lightweight man, wore shoulder pads under his costume so that his appearance would match the bulky appearance of Prohaska.

Prohaska made an appearance on an episode of What's My Line? in 1969, where he wore one of his ape costumes.

Personal life and death Prohaska was born on October 10, 1919 in Budapest, Hungary. He was married to Irene M. Knoke from June 29, 1969 until his death on March 13, 1974. He and his son Robert were killed along with 34 others in the crash of a chartered Sierra Pacific Airlines Convair CV-440 aircraft near Bishop, California, while filming the ABC/Wolper Productions television series Primal Man. The plane flew into a mountain ridge in darkness, and the exact cause of the crash was never determined. Prohaska was cremated and his ashes were interred in the Mausoleum at Woodlawn Memorial Cemetery, Santa Monica.
