Three University professors, Paul H. Hanus, Edwin H. Hall and Edward S. Sheldon '72 will retire from active teaching at the end of the year, and each of them has been appointed professor emeritus by the Governing, Boards of the University.

Professor Hanus was born in Silesia, came to this country at the age of four years, and was graduated from the University of Michigan in 1878. His connection with the University dates from 1891, when he became assistant professor of the History and Art of Teaching. Ten years later he was advanced to a full professorship. He is well-known for his contributions to educational theory and his work in connection with school inquiries and surveys, and he played a large part in the movement which led to the founding of the Harvard Graduate School of Education.
