Henry Slesar was born in Brooklyn, New York City. His parents were Jewish immigrants from Ukraine, and he had two sisters named Doris and Lillian. After graduating from the School of Industrial Art, he found he had a talent for ad copy and design, which launched his twenty-year career as a copywriter at the age of 17. He was hired right out of school to work for the prominent advertising agency Young & Rubicam.
It has been claimed that the term “coffee break” was coined by Slesar and that he was also the person behind McGraw-Hill’s massively popular “The Man in the Chair” advertising campaign.
