During its first years in Moraga, the college nearly went bankrupt, but eventually managed to gain financial security when it was bought by Archbishop John Joseph Mitty, for whom a residence hall is now named. During World War II the college was used by the United States Navy for the training of pilots. Former President Gerald Ford was briefly stationed at the school and served as a naval instructor. The navy erected many buildings, including the world's largest indoor pool, but only one, Assumption Hall, remains on the campus as the school had little use for most of the buildings after the war. Saint Mary's continued to be a male-only school until 1970, when it became coeducational. Since then, more women have come to the college and by 2011, 62% of the students were women.
