Focke-Achgelis was a German helicopter company founded in
1937 by Henrich Focke, and Gerd Achgelis.
The first fully controllable helicopter (as opposed to autogyro) was the
Focke-Wulf Fw 61, demonstrated by Hanna Reitsch in 1936 in Berlin,
In 1937 shareholders of Focke-Wulf pressured Heinrich Focke to leave the
company, so he set up a new business to specialise in helicopters.
