Lloyd C. Douglas was an American author and minister. Religion was a strong influence throughout Douglas's life, and he served as a Lutheran clergyman for many years before changing denominations and becoming a Protestant minister. This religious influence is also clear throughout his work, written largely after his retirement from the pulpit. Douglas's four most popular works are Magnificent Obsession, The Robe, White Banners, and The Big Fisherman, all of which were successful upon publication and were eventually adapted for film. Douglas died in 1951 at the age of 73.
