Henry Preiss

Henry Preiss is a sailplane designer. He was a longtime friend and neighbor of Richard Schreder and they worked together to develop and build several examples each of the RHJ-7 [1] and RHJ-8 two-seat sailplanes, and also the RHJ-9 and RHJ-10. Preiss also finished the Schreder HP-19. [2] [3]

Richard E. Schreder was an American naval aviator and sailplane developer, responsible for design and development of the HP/RS-series kit sailplanes marketed from 1962 until about 1982. Schreder also founded and ran Airmate, a successful drafting supplies company.

The RHJ sailplanes were developed on-the-fly; neither Preiss nor Schreder kept detailed plans or design drawings, and made only what sketches were necessary for the basic engineering validation of the structure.
