Vincent Joseph Dunker (6 December 1878 – 11 March 1974) was a photographer, inventor and camera manufacturer who began his career in Ste. Genevieve, Missouri in the late 1890s. Dunker built a wide variety of cameras, contact printers, photo enlargers, and photo booths over a period of thirty-seven years. In 1924 he began production of his specialty, long roll film cameras intended for taking photos of high school students for yearbooks and individual sale. By the time Dunker built his last camera in 1961 such annual school photography had become routine in high schools throughout the U.S.
Note from Rodger Carter: “If your readers are interested in a more complete biography of Mr. Dunker and the many cameras, enlargers, and contact printers he made, they can visit my website, DigiCamHistory.com (dchis.com) about halfway down the 1950′s page.”
