In the late 1920s, Lewis embarked on a career as a circus performer, only to later opt for a more academic path, culminating in the attainment of a Doctor of Philosophy degree in child psychology from the esteemed Columbia University.
Prior to his transition to the world of acting, Lewis honed his teaching skills and authored two children's books, solidifying his expertise in the realm of pedagogy.
In 1949, a friend's suggestion prompted Lewis to explore his passion for acting, leading him to enroll in the Paul Mann Actor's Workshop in New York City.
Lewis's early career in the entertainment industry involved stints in burlesque and vaudeville theaters across the United States, which ultimately paved the way for his eventual debut on the Great White Way.
As the 1950s unfolded, television was experiencing a surge in popularity, and Lewis capitalized on this trend by securing roles on nearly every live show emanating from his home base of New York City.
Notable among his many television credits are his iconic portrayals of Officer Leo Schnauser on Car 54, Where Are You? (1961) and Grandpa on The Munsters (1964).
Following the conclusion of these popular television shows, Lewis opened a restaurant in New York City's Greenwich Village, aptly named "Grampa's," which became a beloved gathering spot for locals and visitors alike.
In addition to his culinary pursuits, Lewis has also produced a home video for children and made appearances on WTBS in a series of Saturday morning programs designed specifically for young audiences.
