Bill Mumy (born Charles William "Bill" Mumy Jr. on February 1, 1954) appeared on I Dream of Jeannie as Custer Jamison, a neighborhood boy who not only witnesses Jeannie in her harem outfit, but also sees her perform some of her magic, levitating Tony in mid air, and disappearing while he is watching her dance with Tony, in the Season 1 episode "Whatever Became of Baby Custer?"
A former child actor, Bill is perhaps best known for his role as young Will Cartwright in the CBS-TV science fiction show Lost in Space from 1965-68. He played the role Lennier in all five seasons of the syndicated science fiction series Babylon 5.
Mumy is also a musician and is one-half of the popular "novelty rock" duo Barnes & Barnes along with childhood friend Robert Haimer. The duo is perhaps most famous for their song "Fish Heads". He and Haimer co-wrote and starred in an animated short based on this song in 1982.
