The Marjorie May Cowan papers are arranged in one half-size box and date from 1929-1934, 1949, and 1984. The bulk of the papers is comprised of Cowan's diaries. During the years 1932 through 1934 she kept detailed accounts of her social and academic activities and interests. Also among her entries are characterizations of family friends and descriptions of several Northwestern faculty and the courses they taught. Faculty noted include Snyder, Herrold, and Baker Brownell. A few letters and a folder of some of Cowan's course papers, along with her review of F.B. Snyder's, Life of Robert Burgs, complete the series.
