Peter J. Cohen is a New York-based collector of snapshots and vernacular photographs. Cohen began collecting vernacular photography over twenty-five years ago at thrift stores and flea markets. Since then he has amassed a substantial collection of approximately 50,000 photographs which are organized into over 100 categories. The collection spans much of the twentieth century and encompasses many different processes, including gelatin silver, cyanotype, collodion, hand-tinted, chromogenic color, and Polaroids. The stunning collection offers a visual history of amateur photographers’ engagement with the medium. While still avidly collecting, Cohen plans to continue giving away much of his collection to institutions around the world. Cohen has donated significant portions of his collection to museums including the Metropolitan Museum of Art, MoMA, The Art Institute of Chicago, The Morgan Library, and many others.
