Address books, calendars, diaries, letters, postcards, and scrapbooks document Mary Crovatt Hambidge’s activities, interests, work, and relationships. Incoming letters from Jay Hambidge trace the couple’s burgeoning relationship, their travels to Greece, and his developing theory of dynamic symmetry. Letters, incoming and outgoing, estate records, postcards, scrapbooks and family papers of Crovatt-DuBignon-Grandison-Schlatter provide details into Crovatt family genealogy, including family ties to Jekyll Island, and Mary Hambidge’s relationships with family and friends. However they do not document fully Mary’s development from early childhood to adulthood. School work, notebooks, poems, letters, printed material and publications, and writings (including quotes and works by other authors) document Mary’s intellectual development and ideas on a broad range of subjects: art and design; philosophy, religion, and spirituality; modernization, nature, and politics (local and national); and race relations. A variety of materials – computations and measurements, letters, notebooks, published and unpublished manuscripts, and scrapbooks – trace the efforts of Jay Hambidge to develop and promote his theory of dynamic symmetry, and, to a lesser extent, his ties as an artist and illustrator to the arts community. These materials also document the efforts of Mary Hambidge to continue the work begun by Jay Hambidge. Mary Crovatt Hambidge papers are found in boxes 1 through 21, Jay Hambidge papers are found in boxes 22 through 32 and the Crovatt-DuBignon-Grandison-Schlatter papers are found in boxes 33 through 34.
