If you mean in the television show from long ago, it was Theodore Cleaver.
The Cleaver family in the TV comedy, "Leave It to Beaver," Were the parents, June and Ward Cleaver, the older son, Wally, and the younger son, called Beaver by everyone except his teacher, who used his proper personal name, Theodore.
In the old TV show "Leave It To Beaver," Theodore Cleaver got the nickname "Beaver" because his real name was Theodore, which sounds like "Theodore Beaver." His older brother, Wally, initially called him "Beaver" as a mispronunciation of his real name. The nickname stuck and became his commonly used name throughout the show.
