The evolution of radiology at the University of Michigan after Roentgen's discovery in 1895 has had a profound influence on radiology. The school has had notable firsts in medicine: it was among the first of the state-supported universities to have a medical school (1850), had the first teaching hospital owned by a university (1869), and had the first university department of roentgenology (1917). Given these circumstances, teaching and research were early high priorities. The original small hospital, a remodeled private residence in Ann Arbor (1869), proved inadequate and was replaced in 1891 by the Catherine Street Hospital, viewed then as the largest teaching hospital in the nation. This served the medical school well for many years but was succeeded by the magnificent new University Hospital in 1925. Built for $4.4 million with a bed capacity of 700 in a double-Y architecture, it was an entirely new concept in hospital design and was the pride of the state [1].
