Uster Memory

Historical photographs are living witnessing a distant past. Uster, the third largest city in the Canton of Z├╝rich, with over 30 000 inhabitants, is one of the twenty largest cities in Switzerland. The photographs of Julius Gujer (1893-1909), an entrepreneur and gifted photographer, offer an insight into the industrial development of a small Swiss town at the turn of the century. A large collection of 492 of his photos has been made available by the city of Uster on the occasion of the first Zurich Archival Hackday on June 9th, 2017, at the state archives of the Canton of Zurich. 16 random photos drawn from this repository have been turned into an online game application.
