Hans Jacobs (30 April 1907 in Hamburg – 24 October 1994) was a German sailplane designer and pioneer.
Hans also designed a glider-seaplane, the "Sea Eagle", test flown by Hanna Reitsch.
[3] In 1936, Hans developed self-operating dive brakes, on the upper and lower surface of each wing, for gliders.
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.
[4] When the prohibition on German aviation under the Allied occupation ended in 1951, Jacobs designed and marketed a significantly different, updated version of the Kranich.
