Linden, Genesee County, Michigan, businessman and inventor. Papers and photographs largely concerning agricultural and motion picture business interests, especially the Judson Michibean Company and the Photometric Products Corporation.

The Judson collection could be of interest to researchers concerned with the technical development of American agriculture, especially beans, and for those interested in the motion picture industry. Among the papers are patents, technical information, and advertising releases on the development of Judson's mechanized agricultural equipment. This material documents the impact Judson's innovations had on the bean industry. There are also business papers of Ephraim and Russell Judson, which though incomplete, include several suits and financial reports of Judson's companies and features breakdowns on manufacturing and marketing costs for specific years. Also included is a scrapbook and a photo album of Judson's Michibean Company. Donated with the collection and separately cataloged are several issues of the Michigan bean industry publication "The Bean Bag."

Most of the material in the collection which relates to Photometric Products Corporation is legal in nature, and includes evidence and exhibits assembled for the 1953 lawsuit over the motion picture sound development patents. For the most part, the papers concern matters of ownership and patent rights, but some financial and technical information is also included. This material could be very useful in researching the technical development of film or in completing the legal history of the motion picture industry. However, it would need to be supplemented by the court records and evidence submitted by the other parties involved in the controversy.

The collection has been arranged into the following series: Biographical material; Business papers (mainly Michibean Company); Photometric Products Corporation materials; Miscellaneous; and Photographs.
