Michigan Medicine, Ann Arbor

Michigan Medicine, formerly the University of Michigan Health System (UMHS), is the wholly owned academic medical center of the University of Michigan, in Ann Arbor. It includes the U-M Medical School, with its faculty group practice and many research laboratories; the U-M hospitals and health centers, which include the University of Michigan Hospital, C.S. Mott Children's Hospital, Von Voigtlander Women's Hospital, as well as approximately 40 health centers and home care services across southeast Michigan; the clinical programs of the U-M School of Nursing; and the activities of the Michigan Health Corporation, through which U-M partners with other medical centers and hospitals to provide specialized care throughout Michigan.

As a non-profit entity, Michigan Medicine uses positive operating margins to fund continued advances in patient care, education, research, and the facilities needed to support these functions.

In 1869 the University of Michigan opened the first hospital in the country owned and operated by a university, in a house originally built as a professor's residence. In 1876 a new, larger hospital building was opened adjacent to the old one. At the insistence of the Michigan Legislature the new building had two separate departments, one for medicine and the other for homeopathy. In 1891 the hospital again moved to a set of new buildings away from the university campus, on Catherine Street.

In 1925 the university opened a new, much larger 280,000 square feet (26,000 m2) hospital building at a cost of $3.85 million. It was designed by Albert Kahn and built by Thompson-Starrett Company, which had built the Woolworth Building in New York City, the world's tallest at the time. In 1986 this building, known as "Old Main", was replaced by a new one farther away, and it was demolished in 1989.

University of Michigan Rogel Cancer Center (formerly Comprehensive Cancer Center) was founded in 1986, and the Cardiovascular Center opened in 2007 on the site of the "Old Main" hospital.
