In 1950 Irene W. (Mrs. Oscar) Johnson donated $235,000 to Washington University for the establishment of a medical rehabilitation facility as a unit of the McMillan Hospital. In October 1959 the Irene Walter Johnson Institute of Rehabilitation opened at 509 S. Euclid Avenue, between the McMillan Hospital and the Washington University Clinics. Services of the Institute were coordinated through the Washington University School of Medicine’s Department of Preventive Medicine and Public Health.
