Rosenau Hall opened in 1962 to serve as the home of the School of Public Health. The additional space was much needed: at the time it opened, public health classes had been offered in fourteen different buildings around campus. In 1965 it was named for Milton Rosenau, founder of the school and a public health pioneer. Rosenau worked in public health positions in the federal government and then went to Harvard, where he established the nation's first school of public health. After retiring from Harvard he to came to Chapel Hill and founded the School of Public Health, serving as its dean for several years.
