Byron Stewart (born May 1, 1956 in Baxter Springs, Kansas) is an American actor best known for his portrayal of Warren Coolidge in the television series The White Shadow and the television medical drama St. Elsewhere. Stewart, who is 6'8" tall, later reprised the role of Warren Coolidge in another Paltrow-directed series, St. Elsewhere. The explanation was that Coolidge had to give up basketball because of an injury while in his sophomore year at Boston College. Due to his injury, he lost his scholarship, dropped out and became an orderly at St. Eligius Hospital.
