Jerry Lewis was born Jerome Joseph Levitch on March 16th, 1926 in Newark, New Jersey. His father was a Vaudevillian and his mother was a pianist for WOR.

By fifteen, Lewis had developed a "Record Act", miming lyrics to songs while a phonograph played offstage. To supplement his income he worked as a soda jerk at the Paramount Theater while he honed his act. In 1943, Lewis met singer Dino Paul Crocetti thanks to Frank Sinatra’s mother Dolly. They became friends.

Dino Crocetti was born on June 7th, 1917 in Steubenville, Ohio. He spoke only Italian until age five, got bullied for his broken English in school, and eventually dropped out in the tenth grade.

By fifteen Crocetti had bootlegged liquor, worked in a steel mill, served as a croupier at a speakeasy, and was a welterweight boxer. Boxing got him, among other things, a broken nose and a scarred lip. He’d later get the nose fixed.

Dino then worked as a roulette stickman in an illegal casino behind a tobacco shop, and started singing with local bands, calling himself "Dino Martini."

By late 1940 he had begun singing for Cleveland bandleader Sammy Watkins, who suggested he change his name to Dean Martin. In the fall of 1943 he’d begun performing in New York, but was drafted into the military during World War II. Dean served fourteen months before being discharged due to a hernia.

Although they were friends for more than a year, Dean and Jerry didn’t officially team up until debuting at Atlantic City's 500 Club as Martin and Lewis on July 25th, 1946. The highlights of their act included Lewis heckling Martin while he was trying to sing, which ultimately led to them chasing each other around the stage. People loved their improvisational style. And Lewis knew that Martin was his comic equal.

Martin and Lewis’ success at the 500 Club led to a series of well-paying engagements along the Eastern Seaboard, culminating with a run at New York's Copacabana Club. Almost overnight, the two were the biggest smash hit in clubs across the country.
