Dietrich / Dietrich-Gobiet
Richard Dietrich first built a monoplane at his Hanuske works in 1912, and learned to fly a year later. In 1922 produced the DP.1, one of the first light aircraft in Germany. About that time the name was changed to Dietrich-Gobiet, of Kassel. In 1924 built a cantilever biplane resembling a Fokker D.VII, as well as other designs, but by 1925 (when company reverted to original name) was in serious financial trouble, becoming bankrupt in 1927.
