Gilbert and Sullivan productions in this country owe much to the Allen family of Philadelphia. Alfred Reginald Allen (1876-1918), a noted neurologist and neurosurgeon, founded the Savoy Company in this city in 1901 to stage the works of W.S. Gilbert and Arthur Sullivan.
Allen earned his degree from the University of Pennsylvania Medical School in 1898, and published medical papers and articles mostly about his specialty - injuries of the spinal cord. He also was heavily involved in the theater and wrote numerous operettas, some of which were published.
After seeing Gilbert and Sullivan shows in England, he helped form and conduct the Savoy Company's productions. Allen, however, seems to have abandoned his work in the theater in the early part of the 20th century to focus on his medical career.
