Leave It to Beaver is an American television situation comedy that follows the misadventures of a suburban boy, his family and his friends. It stars Barbara Billingsley, Hugh Beaumont, Tony Dow and Jerry Mathers ("as The Beaver", as the opening credits put it).
CBS first broadcast the show on October 4, 1957, but dropped it after one season. ABC picked it up and aired it for another five years, from October 2, 1958, to June 20, 1963.
The show is built around young Theodore "Beaver" Cleaver (Jerry Mathers) and the trouble he gets himself into while navigating an often-incomprehensible, sometimes illogical world. Supposedly, when he was a baby, his older brother Wallace "Wally" (Tony Dow) mispronounced "Theodore" as "Tweedor". Their firm-but-loving parents, Ward (Hugh Beaumont) and June Cleaver (Barbara Billingsley), felt "Beaver" sounded better. Conversely, Mathers has said that the real reason for the name "Beaver" is that one of the show's writers, Joe Connelly, had a shipmate named "The Beaver" in World War II; from that came the family's name, "Cleaver."
Beaver's friends include the perpetually apple-munching Larry Mondello (Rusty Stevens) in the early seasons, and, later, Gilbert Bates (Stephen Talbot), as well as the old fireman, Gus (Burt Mustin). His sweet-natured-but-no-nonsense elementary school teachers are Miss Canfield (to whom Beaver declares his love in the episode entitled "Beaver's Crush") (Diane Brewster), Miss Landers (Sue Randall) and Mrs. Rayburn (Doris Packer), the school's principal. In the early seasons, Beaver's nemesis in class is Judy Hensler (Jeri Weil).
