Margaret Mann (librarian)

Margaret Mann (April 9, 1873 – August 22, 1960) was a noted librarian and teacher who influenced the field of cataloging for almost fifty years. The bulk of her career was spent as a professor at the University of Michigan. She was hired as one of the first three full-time faculty members in the department of library science at Michigan in 1926 and retired in 1938. In 1999, American Libraries named her one of the "100 Most Important Leaders We Had in the 20th Century".
