Most of this correspondence is from others, directed to Washburn, but a few of his letters are also included. It also includes some correspondence directed to Margaret Washburn after his death. The largest single set of correspondence is from Ludwig Emge, a California physician who was a great admirer and collector of Washburn’s work. Other interesting names in the correspondence include art dealer Frederick Koeppel; fellow artists including Howard Chandler Christy, James McBey, and John Taylor Arms; Ada Galsworthy, widow of British novelist John Galsworthy; Albert Besnard, Washburn’s teacher in etching; and Frank Weitenkampf, chief of the art and print departments of the New York Public Library. From the deaf community, there are letters from David Peikoff, Ben Schowe, and Gallaudet president Leonard Elstad, as well as some schools for the deaf. There is some correspondence from politicians, including the governor of California and ambassadors to England and France, giving their support to exhibits of Washburn’s work. Of particular interest may be the letters to journalist Eleanor Ferris, who Washburn apparently had romantic interest in. These include some letters he wrote while on his 1920s trip to the Marquesas that contain some local color and anecdotes.
