Dr. James Kildare is a fictional character in a series of films in the late 1930s and early 1940s, an early 1950s radio series, a 1960s television series of the same name and a comic book based on the TV show, and a short-lived second 1970s television series. The character was created by the author Frederick Schiller Faust, under the pen name Max Brand.
Lionel Barrymore and Lew Ayres performed a scene from their soon-to-be-released film, Young Dr. Kildare, on MGM's "Good News of 1939" program, October 13, 1938.
In the summer of 1949, MGM reunited Lew Ayres and Lionel Barrymore to record the radio series, The Story of Dr. Kildare, scripted by Les Crutchfield, Jean Holloway and others. After broadcasts on WMGM New York from February 1, 1950 to August 3, 1951, the series was syndicated to other stations during the 1950s. The supporting cast included Ted Osborne as hospital administrator Dr. Carew, Jane Webb as nurse Mary Lamont and Virginia Gregg as Nurse Parker, labeled "Nosy Parker" by Gillespie, with appearances by William Conrad, Stacy Harris, Jay Novello, Isabel Jewell and Jack Webb.
