Association of American Universities as an affiliate member and it was made a full member by 1944. Between 1946 and 1947, in infamous uranium experiments researchers at the university injected uranium-234 and uranium-235 into six people to study how much uranium their kidneys could tolerate before becoming damaged. In 1955, the separate colleges for men and women were merged into the college on the River Campus. In 1958, three new schools were created in engineering, business administration, and education. The Graduate School of Management was named after William E. Simon, former Secretary of the Treasury in 1986. He committed significant funds to the school because of his belief in the school's free market philosophy and grounding in economic analysis. Financial decline and name change controversy Following the princely gifts given throughout his life, George Eastman left the entirety of his estate to the university after his death by suicide. The total of these gifts surpassed $100 million, before inflation, and, as such, Rochester enjoyed a privileged position amongst the most well-endowed universities. During the expansion years between 1936 and 1976, the University of Rochester's financial position ranked third, near Harvard University's endowment and the University of Texas System's Permanent University Fund.

At the same time, the preeminence of the city of Rochester's major employers began to decline.

The study concluded a name change could be beneficial because the use of a place name in the title led respondents to incorrectly believe it was a public university, and because the name "Rochester" connoted a "cold and distant outpost." Reports of the latter conclusion led to controversy and criticism in the Rochester community. Ultimately, the name "University of Rochester" was retained. Renaissance Plan In 1995, university president Thomas H. Jackson announced the launch of a "Renaissance Plan" for the college that reduced enrollment from 4,500 to 3,600, creating a more selective admissions process. The plan also revised the undergraduate curriculum significantly, creating the current system with only one required course and only a few distribution requirements, known as clusters. Part of this plan called for the end
