In 1883, with its first class, the College of Dentistry at the University of Iowa began a tradition of mounting individual portraits of graduates on photo boards. Over time, these boards made their home in the basement of the college’s modern building, where they were silently deteriorating until last year. Today, these images — part of university’s heritage — have been preserved in the UI Libraries’ Dentistry College Class Photos Collection.
