Tank Hall, formerly known as Tank Home, was erected in 1896 as a home for children of missionaries of the American Board of Commissioners for Foreign Missions. It was named in memory of Mrs. C.L.A. Tank of Green Bay Wisconsin, who gave $10,000 toward its construction. For ten years, 1922 to 1932, it was used as a hall of residence for women, with accommodations for forty-four persons. This use was resumed in 1935. At the present time it accommodates forty-seven women. [Forty-two students live in Tank, and an additional forty take meals in the co-op.]
