About Bill Mumy
Charles William Mumy Jr. (; born February 1, 1954) is an American actor, writer, producer, and musician. He came to prominence in the 1960s as a child actor (credited as "Billy Mumy"), whose work included television appearances on Bewitched, I Dream of Jeannie, The Twilight Zone, Alfred Hitchcock Presents, and a role in the film Dear Brigitte, followed by a three-season role as Will Robinson in the 1960s sci-fi series Lost in Space. Mumy later appeared as lonely teenager Sterling North in the film Rascal (1969) and Teft in the film Bless the Beasts and Children (1971). In the 1990s, Mumy performed the role of Lennier in all five seasons of the sci-fi TV series Babylon 5 and narrated the Emmy Award–winning series Biography. Mumy is also a guitarist, singer, songwriter, and composer. He is an Emmy nominee for original music in Adventures in Wonderland (1992). As a musician, Mumy performs as a solo artist, an occasional guest performer, and formerly as half of the duo Barnes & Barnes before bandmate Robert Haimer died in 2023. From 1988 through the 1990s he performed at San Diego Comic-Con and other comics-related events as part of the band Seduction of the Innocent (named after the titular book by Fredric Wertham). The band released one CD, The Golden Age. Mumy was reportedly the first choice to portray Eddie Munster in the 1964 CBS situation comedy The Munsters, but his parents objected to the extensive makeup requirements. Mumy guest starred in an episode of NBC-TV's I Dream of Jeannie, "Whatever Became of Baby Custer?" (1965).
