Lee Pierce Butler
Lee Pierce Butler (December 19, 1884 – March 28, 1953) was a professor at the University of Chicago Graduate Library School. He was one of the first to use the term "library science" (along with S. R. Ranganathan), by which he meant the scientific study of books and users, and was a leader in the new social-scientific approach to the field in the 1930s and 1940s.
