The Wayne State University School of Medicine (WSUSOM) currently hosts an enrollment of more than 1,500 medical students in undergraduate medical education, master's degree, Ph.D., and M.D.-Ph.D. programs and courses encompass 14 areas of basic science. WSUSOM traces its roots through four predecessor institutions since its founding in 1868. According to U.S. News ranking, the school ranks 70th nationally in its research activities.The Detroit College of Medicine was founded in 1868 in a building on Woodward Avenue. The Michigan College of Medicine was incorporated in 1879 and offered classes in the former Hotel Hesse at the intersection of Gratiot Avenue, Madison Avenue and St. Antoine Street. In 1885, the two schools merged to form the Detroit College of Medicine and occupied the former Michigan College of Medicine building. The college was reorganized and refinanced as the Detroit College of Medicine and Surgery in 1913, and five-years later, came under control of the Detroit Board of Education. In 1933, the Board of Education joined the Detroit College of Medicine and Surgery with the colleges of Liberal Arts, Education, Engineering, Pharmacy, and the Graduate School to form an institution of higher education called the Colleges of the City of Detroit. This was renamed Wayne University in 1934 and became a state-chartered institution, Wayne State University, in 1956. The dean is Dr. Mark E. Schweitzer.
