"I studied under a surgeon named Joseph Bell. He repeated one lesson over and over. We must learn to use our eyes."―Arthur Conan Doyle[src]
Joseph Bell was a surgeon who was once the teacher of Arthur Conan Doyle during the author's medical career. Conan Doyle used Bell as basis for his creation of detective Sherlock Holmes, which he explained over tea to a young Indiana Jones in April, 1912.
Bell had repeatedly told his students the importance of using their eyes and in turn Conan Doyle passed on Bell's words to Jones, noting that it would be good advice for both a detective and an archaeologist.
