Peter Lind Hayes was the son of entertainer/nightclub entrepreneur Grace Hayes (1896-1989). Hayes was nine years old when he joined his mother's vaudeville act, doing an impression of Hollywood child star Jackie Coogan. He then spent several years as the star attraction of the Grace Hayes Lodge in the San Fernando Valley. In 1938, he made the first of his sporadic film appearances, and in 1940, he married his future stage and screen partner, singer/actress Mary Healy. While serving with distinction in the Army Air Force, Hayes was featured in the 1944 20th Century-Fox feature Winged Victory. From 1946 onward, the songs-and-snappy-patter team of Peter Lind Hayes and Mary Healey was a top New York nightclub and theatrical attraction. They extended their activities to TV in 1949, starring in such variety series as Inside the USA With Chevrolet (1949-50), The Stork Club (1950), The Peter Lind Hayes Show (1950-51, with Mary--originally titled Peter and Mary) and Star of the Family (1951). Their last regular TV gig was the semiautobiographical 1960 sitcom Peter Loves Mary (1960). In addition, Hayes and Healey starred in the 1958 Broadway play Who Was That Lady I Saw You With?, while Hayes soloed as Arthur Godfrey's TV and radio summer replacement and as one of the post-Paar, pre-Carson hosts of The Tonight Show. While his film career never attained the heights of his activities elsewhere, Hayes enjoyed at least one truly memorable screen role: Mr. Zalbedowski in the cult musical fantasy 5000 Fingers of Dr. T, co-starring wife Mary and Hans Conried. Active in a number of entertainment fields, Peter Lind Hayes was the author of three books and several magazine and newspaper articles, and served as producer-host of the 1975 anthology series When Television Was Live.
