Dr. Hudson's Secret Journal is an American medical drama which aired in syndication from 1955 to 1957. It was based on a 1939 book of the same name by Lloyd C. Douglas, that was a prequel to his 1929 novel Magnificent Obsession. A total of 78 episodes were produced. Hudson, a neurosurgeon, was a widower who lived with his daughter, Kathy, and their housekeeper, Mrs. Grady. His work at Center Hospital involved use of his "strange and rather mysterious gift" to help patients psychologically. In 1955 a nationwide competition was held in TV Guide to find a young actor to play Dr. Hudson's protégé, Tim Watson, for several episodes. Those entering had to submit a photo and recording in which they read emotional dialogue. The winner was a young actor named Joe Walker.
