Founded by Henry Wilhelm and Carol Brower in 1995, WIR was established based upon the research done for Wilhelm's 1993 book on photograph preservation (co-authored by Brower) The Permanence and Care of Color Photographs: Traditional and Digital Color Prints, Color Negatives, Slides, and Motion Pictures. The firm's work now involves testing of inkjet materials and various digital output used in the industry and by fine-art printing presses. In addition to its raw research, WIR consults for a wide variety of clients in the photography, archival, and digital print media fields. Current and past clients include the Museum of Modern Art, among others, as well as manufacturing companies Lexmark, Hewlett-Packard, Fuji, and Epson; additionally, the Bill Gates' owned Corbis Corporation in New York City, owner of the 20 million image Bettmann Archive. Wilhelm himself serves on several boards and associations in the photographic and digital media fields, including the Board of Editorial Advisors for Photo-Electronic Imaging magazine, the Photographic Materials Group of the American Institute for Conservation, and the American Nationals Standards Institute. Wilhelm was a founding member and Secretary of the ANSI subcommittee responsible for writing the ANSI IT9.9 standard on test methods for measuring the stability of color photographs.
