Robert Carl Sticht (8 October 1856 – 30 April 1922) was an American metallurgist and copper mine manager, active in Colorado and Montana, U.S.A. and in Tasmania, Australia. Sticht was the developer of the first successful purely pyritic smelting in the world.[1] He was also an important book and art collector, a large part of whose collections were acquired by the Public Library of Victoria and the National Gallery of Victoria in the 1920s.
