The Jacobs School of Music of Indiana University in Bloomington, Indiana, is an undergraduate and graduate institution for the study of music established in 1921. Until 2005, it was known as the Indiana University School of Music. It has more than 1,600 students, approximately half of whom are undergraduates, with the second largest enrollment of all music schools accredited by the National Association of Schools of Music. In 1907, Charles Campbell arranged for a recital of the Schellschmidt Quartet of Indianapolis, the proceeds of which established a music fund, "to lead ultimately to the equipment of a school of music in the university." In 1909, he offered a series of noncredit lectures on the history of music, which eventually led to a full fledged music department. In 1919 Barzille Merrill took the position of department head and worked to create a separate school of music. He campaigned for a new music building as well, which was dedicated in 1937, and renamed Merril Hall in 1989. In 1921 the Department of Music officially became the School of Music. In 1938 Robert L. Sanders was appointed Dean and remains the school's youngest-ever dean.
