Peter Löwenbräu Griffin is the main character of the American animated sitcom Family Guy. He is voiced by cartoonist Seth MacFarlane and first appeared on television, along with the rest of the family, in the 15-minute short on December 20, 1998. Peter was created and designed by MacFarlane himself.
MacFarlane was asked to pitch a pilot to the Fox Broadcasting Company based on Larry & Steve, a short made by MacFarlane which featured a middle-aged character named Larry and an intellectual dog, Steve. After the pilot was given the green light, The Griffin family appeared on the episode "Death Has a Shadow". Peter is married to Lois Griffin and is the father of Meg, Chris, and Stewie. He also has a dog named Brian, with whom he is best friends. He has worked at a toy factory, and at Quahog's Brewery. Despite the suburban blue-collar routine of his life, he has had a number of remarkable experiences. Peter's voice was inspired by a janitor that MacFarlane heard at his school. His appearance was a redesign of the protagonist Larry from MacFarlane's previous animated short films The Life of Larry and Larry & Steve. He has appeared in several pieces of Family Guy merchandise, including toys, T-shirts and a video game, and has made crossover appearances in other shows, including The Simpsons, South Park, Drawn Together, American Dad!, and the Family Guy spin-off The Cleveland Show.
