According to Dr. Henry Hurd's 1916 Institutional Care in the United States and Canada, this institution held 41 patients at the time of writing. "Private patients could be admitted to the ward in the same manner as public. The charge for their maintenance was to be paid by the regents of the State University." The building itself was designed by architects Mason and Albert Kahn in 1906, and Kahn worked on additions in 1913. The first patients were transfered from the state mental hospitals at Kalamazoo and Pontiac.

In the late 1890s, U-M Professor of Nervous Diseases and Electrotherapeutics William J. Herdman (M.D. 1875) set the wheels in motion to build, at the University, a psychopathic hospital for the care and study of mental illness. In 1901 the Michigan state legislature allocated the funding for the facility, and in 1906 the State Psychopathic Hospital opened its doors. The hospital was among the first of its kind in the nation — one intended to provide diagnosis and research on mental diseases rather than custodial care. It contained state-of-the-art research equipment, including a laboratory in which psychiatrists trained in pathological examination studied brain tissue sent from hospitals all over Michigan.
