Al Pearce became one of the most successful entertainers on radio with his famous knock on the housewife's front door and his remark, "Nobody at home, I hope, I hope, I hope."
He began his career with the Don Lee Radio Network in 1926. His program originated with KFRC in San Francisco and later was carried by networks to Fresno and Los Angeles. The daytime show, "The Happy Go Lucky Hour" — also known as "Al Pearce and His Gang" — had one of the first studio audiences.
In 1946, with the advent of television, Pearce took his show to Channel 2.
