The Mary D. Cason Papers consist of the academic and personal papers of Mary Cason, who taught at the Maryland School for the Deaf, from 1926-1946. The collection, which includes approximately 3,400 pages, dates from 1909-1952. The bulk of the collection falls into the period when Cason was in charge of the primary and intermediate departments of the Maryland School for the Deaf. Included are teacher meeting notes, plan books, programs from demonstrations, programs of commencement activities, and a manuscript on deaf education. Cason had a special interest in speech development. Notes specifically relating to stammering, speech, articulation, and stuttering can be found in the collection. Information on the Radio Ear is also included in this series. The remainder of the collection consists of Cason’s personal papers. Cason kept a personal diary from 1904-1905. She also recorded “dinner stories” for a year, 1921-1922. The last component of her personal papers is three scrapbooks: Maryland School for the Deaf, 1939-1945; Nazi Germany, 1939-1945; and miscellaneous items, 1938.
