Peter's audio career was launched in high school as an announcer oh the school radio system, from which he was banished after his unauthorized announcement that the Chinese communists had taken over the school and that a "Mandatory Voluntary assembly was to take place immediately." The principal who fired him, Russel Rupp, was to inspire the character of Principal Poop on "Don't Crush That Dwarf".

It was in high school that Peter formed his first recording group, "The Four Candidates" turning out a comedy cut-up single "Attention Convention" parodying the 1956 democratic convention. Released on Buddy records, it got air play in Cleveland and Pittsburgh.

At college, Peter was managing editor of the Yale comedy magazine, wrote the lyrics for two musical collaborations with Austin Pendleton, both of which starred Phil Proctor, graduated scholar of the house in economics and played point guard for the liberal basketball league, whose members have since lost their dribble but not their politics.

Peter spent two graduate years at Yale as a Carnegie teaching fellow in economics and as the Eugene O'Neill playwriting fellow at the drama school. After a six-month stint as a grunt in the U.S. Army's 349th general hospital unit he went to Berlin on a Ford foundation fellowship to join Tom Stoppard, Derek Marlow and Piers Paul Read at the Literarisches Colloquium Berlin. There he wrote and directed his first film, "Flowers" and connected with the Living Theatre, a major influence on his art.

Peter worked briefly in London with Spike Milligan and the BBC before returning to America in 1966. Mr. Bergman secured a nightly radio show on Pacifica's KPFK in Los Angeles, around which the Firesign Theatre was born.

Peter invented the word "Love-In" and threw the first such event in April of 1967 in Los Angeles, attracting 65,000 people and blocking freeways for miles. This so impressed Columbia Records producer, Gary Usher that he offered the Firesign their first record contract.

In the 70's Peter diversified his comic career as the president of a film equipment company and helped produce a machine for viewing angio cardiograms and measuring the blockage of the arteries of the heart.

In the 80's Peter turned to film and tape producing the comic feature "J-Men Forever" with Phil Proctor and a series of television shows with various members of the Firesign.

Since 1995 Peter has been touring the country as a "high tech comedian", delivering lectures and keynote speeches to computer oriented companies and conventions. He is presently working on the Firesign's latest disc and publishing the web site for one of the candidates for Mayor of Los Angeles.
