Pete Campbell works in the accounts department at Sterling Cooper. He lives in a Park Avenue apartment with wife Trudy, whose father is well off. Pete is a graduate of Deerfield Academy prep school and isn't the most secure guy in the world.
His father died in the crash of an American Airlines jetliner.
Early in season one, Pete slept with Peggy. The result was a baby, which Peggy gave away and which Pete learned about on the second season finale.
