Actor. Born Jonathan Charasuchin, the son of Russian immigrants, in the Bronx, New York he grew up in Brooklyn. Harris received a pharmacology degree from Fordham University, but after seeing several local plays he decided he wanted to pursue acting. To correct his Brooklyn accent he watched hundreds of English movies, changed his name, and then joined the Millpond Playhouse in Long Island. His Broadway debut was in 1942's 'Heart of the City.' During WWII he toured with the USO in the Pacific Theater. Upon his return he landed a co-starring role in the 1957-1960 series 'The Third Man'. Other TV roles followed including guest spots in 'The Outlaws,' 'Bonanza' and a regular part in 'The Bill Dana Show.' In 1965 he was cast in his most famous role, Dr. Zachary Smith in the pilot for 'Lost in Space.' TV Guide proclaimed Harris the best supporting actor of 1966. With the unexpected cancellation of the series, Harris found himself fighting typecasting. He found guest roles in 'Night Gallery,' 'Bewitched,' 'Ghost and Mrs. Muir,' 'Sanford and Son' and 'Get Smart.' By 1982 he all but retired from on screen performances and devoted himself to voice-over work. His voice was heard in numerous commercials and cartoons including 'Darkwing Duck', 'Freakazoid!', 'Buzz Lightyear of Star Command', 'Toy Story 2' and 'Hubert's Brain.' He also provided the voice for the fabulously smarmy Cylon, Lucifer, on the original 'Battlestar Galactica'. Harris reprised his role as Dr. Smith in the one-hour TV special 'Lost in Space Forever' in 1998. His last major role was in 'A Bug's Life.' Harris died at Encino Medical Center from a blood clot that reached his heart after he was hospitalized for an unrelated illness. He was attended by Gertrude Bregman, his wife of 64 years.
