Robert W. Gundlach (September 7, 1926 – August 18, 2010) was an American physicist. He is most noted for his prolific contributions to the field of xerography, specifically the development of the modern photocopier. Gundlach helped transform the Haloid Company, a small photographic firm, into the thriving Xerox Corporation. Over the course of his 42 year career with the company, he contributed over 155 patents, making photocopying technology more affordable and practical. In 1966 Gundlach was named Xerox’s first Research Fellow, the highest non-managerial that could be achieved by a Xerox scientist. After his retirement in 1995, he was granted several patents associated with his hobbies, including a snow-making system and a special backpack.
