Chubby comedy actor best remembered for his role as the gullible Pvt. Dwayne Doberman in the classic sitcom The Phil Silvers Show (1955) (aka "Sergeant Bilko").
His last role was as a truck driver in The Thrill of It All (1963), and in 1964, he unsuccessfully tested for the role of Uncle Fester in the TV series The Addams Family (1964).
Because of Gosfield's popularity, DC Comics published 11 issues of a Private Doberman comic from 1957-60.
In his 1973 autobiography, Phil Silvers said that Gosfield had a pomposity and condescension off-screen, behaving "like Clark Gable playing a fat man.".
At 5'2" and over 200 pounds, Gosfield never married, and had once told TV writer Bert Resnik that he was too ugly to get married. Despite that statement, he received the "TV Bachelor of the Year Award" by the Bachelor and Bachelorettes Society of America in 1957.
He became ill and was promptly sent to Lenox Hill Hospital in New York City. He had very high blood pressure and diabetes and what he thought was temporary blindness. The staff discharged him to a new place, the Will Rogers Memorial Hospita in, Saranac Lake, NY, an institution that has treated show biz people with diseases, without charge, since the 1920s. From here he was sent to see specialists at the Physicians' Hospital in Plattsburgh, NY, but later returned to the Will Rogers Memorial Hospital.
