 Kelleher's directorship also saw an increasing focus on photography as an important element of the museum's collections.David Hunter McAlpin, Class of 1920, gave a major collection of photographs to the museum in 1971 as well as endowing a fund for further purchases and a professorship, the first endowed chair in the history of photography in the country.That professorship was occupied by Peter Bunnell, who would go on to succeed Kelleher as director in 1973.
