Collection of over 500 images, mostly single photographs but also some newspaper cuttings and a commercial photo album. The largest parts of the collection relate to the political and academic careers of Eoin MacNeill and his son-in-law Michael Tierney, with a strong emphasis on important events at University College, Dublin between 1943 and 1965, such as presentations, conferrals, openings, and ceremonies to mark developments on the new campus at Belfield. Smaller series of photographs contain private family shots.
