Hans Jacobs (30 April 1907 in Hamburg – 24 October 1994) was a German sailplane designer and pioneer. In 1936, Hans developed self-operating dive brakes, on the upper and lower surface of each wing, for gliders. He designed the DFS 230 used in the Battle of Fort Eben-Emael.
The DFS Olympia Meise was selected in 1939 as the glider for the 1940 Summer Olympics, but the games were cancelled. The design was taken up after the war and produced in large numbers in the UK by Elliotts of Newbury, in France by Nord Aviation, in the Netherlands and in Switzerland.
