Hans Berger, a noted Swiss inventor, formed Berger-Helicopter, to develop a series of light helicopters of his own design. The BX-50

Besides these two machines, Berger's other inventions were a jet-powered car, and numerous other helicopter designs. Professionally, Berger was the sales representative for Brantly in Switzerland and Liechtenstein.
