Best known as legendary talk show host Johnny Carson’s sidekick on The Tonight Show, Edward Leo Peter McMahon, Jr., was born March 6, 1923, in Detroit, Mich., and grew up in Lowell, Mass. A graduate of Boston College and The Catholic University of America, McMahon began his television career in Lowell at a small AM station. He’d later join WCAU in Philadelphia as, primarily, a game show host.

It was as a game show announcer that McMahon met Johnny Carson.

Carson was the host, and the game show was Who Do You Trust?. The dynamic duo left the game show to take on The Tonight Show. And the rest, as they say, is history.

Throughout the years, McMahon has made a larger name for himself as a pitchman and variety show host. For more than a decade, he was the host of Star Search, an ancestor to such shows as American Idol. He also starred alongside friend Dick Clark on the popular mid-80s to late-90s TV Bloopers and Practical Jokes. Did You Know?
