Lyndeck, a former college professor, spent well over a dozen years in stock and regional theater roles before making his Broadway debut in the original production of 1776. After originating the role of John Witherspoon, Lyndeck went on to play Stephen Hopkins, Dr. Lyman Hall, and Charles Thomson before ending up on tour as John Dickinson. His other Broadway credits include Mrs. Warren's Profession, A Doll's Life, Merlin, and Into the Woods (as Cinderella's Father).
His best-known role is the evil Judge Turpin in the original production of Stephen Sondheim's Sweeney Todd, which he also repeated for the first national tour, the 1980 television broadcast, and a 1994 production at the North Shore Music Theatre. He earned a Drama-Logue Award for his performance in the tour's Los Angeles berth. He followed up Sweeney Todd with another Stephen Sondheim musical, Into The Woods, originating the role of Cinderella's father.
