The Personal Files series is comprised of three subseries. The first and most substantial, General Personal Files subseries, 1927-1944 (14.4 cubic ft.), Acc. 6, consists of correspondence regarding company matters personally handled by Edsel Ford and activities of special interest to him. Researchers, however, should not be misled by the title. The records are not entirely personal files in the usual sense, but often relate to subjects officially handled by Edsel Ford in the course of company business as well as activities that personally interested him or in which he was personally involved. The subseries is arranged chronologically by year and then alphabetically by correspondent name. Interspersed are subject and designated name files. After 1931, the number of subject and designated name files increase, creating a gradual change from a pure alphabetical name file to a predominately subject file. Topics include the American Legion, Automobile Manufacturers Association, the Detroit Air Olympics, Indianapolis Motor Speedway, National Automobile Chamber of Commerce, National Air Tour, patents and trademarks, Ford dealers and Ford branches, and records of monetary and automotive contributions. There are also several folders of condolence letters arranged alphabetically that were received by Ford Motor Company when Edsel Ford died in 1943. The Edison Institute Construction records subseries, 1929 (8.8 cubic ft.), Acc. 6, consists of architect and contractor records, cost certificates, and invoices relating to the Edison Institute (now The Henry Ford) in the year in which it was dedicated. Companies represented include Alberene Stone Company, Gray-Knox Marble Co., Rayl Company, and the architectural firm, Robert O. Derrick. The President's Birthday Ball Treasurer's Records subseries, 1935-1940 (2 cubic ft.), Acc. 6, are records compiled during the period when Edsel Ford served as treasurer of the Detroit Committee for the National Committee for Birthday Balls, which was sponsored by the National Foundation for Infantile Paralysis and held annually on January 30th, Franklin D. Roosevelt's birthday. The subseries consists of correspondence, reports, documents on disbursements, invoices, bank statements, and donation letters from 1935 to 1940.
