Henry William Faust (May 1850 - March 5, 1915), publishing as 'H. W. Faust,' was a San Francisco-based cartographer who for many years (c. 1882 - 1903) published a pocket map and guide to San Francisco and occasionally other maps. Faust was born in Glasgow, Missouri of German-American parentage. He moved to San Francisco, then Oakland, sometime in the 1870s. Though his path to cartography and publishing are unknown, Faust's earliest guide and map were published in 1882. He also was involved in civic organizations. In his later years, he became an active amateur astronomer, contributing to the local publication Sidereal Messenger, a Monthly Review of Astronomy.
