William F. Slocum (1888-1917), pastor of the First Congregational Church in Baltimore, Maryland, became the president of Colorado College in 1888. Slocum was a graduate of Amherst College and Andover Theological Seminary. During his presidency, the college grew from 50 students to 500 and from a single building to sixteen. His wife, Mary Slocum, founded CC's Woman's Educational Society. After an investigation into what came to be known as the "Slocum Affair," the Board of Trustees requested his resignation. Slocum then spent a year abroad, during which time the Board of Trustees appointed professors Florian Cajori, Edward C. Schneider, and John C. Parish to take over his administrative duties. At the end of the 1916-1917 school year, Slocum officially resigned, and he and Mary retired to Newton Center, Massachusetts.
