Jerry Mathers played clean-cut kid Theodore "Beaver" Cleaver in the TV series Leave It To Beaver from 1957 through 1963. The show's successful first run led to extensive reruns, where the show and 'the Beaver' became pop culture icons. In 1984 Mathers reprised the character as an adult in the 1983 TV movie Still the Beaver and the cable TV series The New Leave It To Beaver (1985-89).

Extra credit: Joining Jerry Mathers in the original cast of Leave It To Beaver were: Barbara Billingsley (1915-2010) as Beaver's mother, June Cleaver; Hugh Beaumont (1909-1982) as his father, Ward Cleaver; Tony Dow (born 1945) as his brother, Wally Cleaver; and Ken Osmond (born 1943) as troublemaking chum Eddie Haskell.
