Mary E. Gawthorpe was a British suffragist who was an organizer for the Women's Social and Political Union (WSPU) from 1906 to 1912. Following her immigration to the United States in 1916, she was involved in a number of American social and political movements, including women's suffrage and labor education. Her papers cover the period of her involvement with the militant British suffragettes as well as some of her activities in the United States. Materials in this collection include her diaries and correspondence, subject files on the WSPU and her other activities on behalf of women's suffrage, and printed materials on women's suffrage such as cartoons, drawings, and other ephemera.
