(December 5, 1930 - June 5, 1991) U.S.A.
Born in Los Angeles, California, as Frederick Lawrence Kert. A former chorus boy, as a child, he appeared in the film Time Out for Lessons (1939) and was a stunt double for Roddy McDowell in Lassie Come Home (1943). As part of a group called The Upstarts, Kert made his Broadway debut in the revue Tickets Please! (1950). He made an uncredited appearance in the film version of Gentleman Prefer Blondes (1953), and returned to Broadway in the cast of John Murray Anderson's Almanac (1953).
A handsome, silvery voiced tenor, he was soon in demand. Kert created the role of Tony in Bernstein and Sondheim's West Side Story (1957), introducing "Something's Coming" and sharing the memorable duets "Tonight" and "One Hand, One Heart" with Carol Lawrence. They repeated their roles in the 1960 revival.
Kert played young groom Gerry Siegel in the short-lived Broadway musical A Family Affair (1962), and was featured in Breakfast at Tiffany's (1966) - which closed in previews. He took over the role of Cliff in the long-running Cabaret in 1968, and survived the one-performance disaster La Strada (1969). Kert took over the lead role of Bobby one month into the run of Stephen Sondheim's Company (1970), earning his only Tony nomination.
He repeated that task in the original London cast soon afterward. Kert was featured in the Broadway revue A Musical Jubilee (1975) and the replacement cast of Side By Side By Sondheim (1977), and made his final Broadway appearance as the ambitious immigrant politician Nathan Hershkowitz in Rags (1986). Kert's only musical film role was as Liza Minnelli's dream agent in the "Happy Endings" sequence of New York, New York (1977).
Shortly after appearing with Carol Lawrence in a joint cabaret act, Kert died in New York City, due to complication from AIDS at age 60. His sister was singer Anita Ellis.
