The Sächsische Maschinenfabrik in Chemnitz was one of the most important engineering companies in Saxony in the second half of the 19th century and the first two decades of the 20th century. Including its various predecessor businesses, the firm existed from 1837 until its liquidation in 1930, and individual branches of the company taken over by others continued to operate until 1990. The company is closely linked with the name of its founder and long-time manager, Richard Hartmann, whose name formed part of the new company title in 1898: the Sächsische Maschinenfabrik vormals Richard Hartmann.

Richard Hartmann was a German engineering manufacturer.
