During the early 1950s Leonard wrote jokes for Milton Berle and then the Jackie Gleason show. It was his brainwave that turned ​The Honeymooners from a sketch in the Gleason show to a fully fledged hit comedy in its own right!  After his successful spell with Gleason, Leonard moved on to the Bilko show. He stayed for a year, writing alongside Nat Hiken et al.  Among the great shows that he contributed to were, The Face on the Recruiting Poster - A Mess Sergeant Can't Win - Doberman's Sister - The Song of the Motor Pool and Bilko's Tax Trouble.

He was then given the opportunity of writing and directing The Steve Allen Show for the next four years!!

For nine years in the 1950s, Leonard was part of three of the most successful US comedy shows of all time. 

Leonard won many awards - Emmys, Peabodys, Golden Globes.

The next comedy he was involved with was ​Get Smart - Leonard wrote scripts and was also the Executive Producer on this hit Mel Brooks comedy, from 1965 to 1968. His overall screen credits are too numerous to mention, needless to say his screenwriting career was sublime!

Leonard went on to be the senior vice president of Price Stern Sloan (PSS). Along with Price and their partner, Larry Sloan, he expanded the company to publish children's books, novelty formats, and humour. Proprietary brands, in addition to Mad Libs include Wee Sing, Mr. Men & Little Miss, Serendipity, Crazy Games, and Doodle Art. The company was purchased by The Putnam Berkley Group in 1993, and in 1997 the offices were moved to New York. PSS publishes approximately 75 titles per year.
