The story
Architects William G. Malcomson and William E. Higginbotham formed a partnership in 1890.
The firm was retained by the Detroit Board of Education in 1895, and between 1895 and 1923 had designed over 75% of the school buildings in Detroit. The firm remained in business under various names until the present.
