Originally Stearman Aircraft Company, formed at Venice, California, by Lloyd Stearman in 1927.

Stentzel Schwingenflieger

Arthur Stentzel of Hamburg-Altona, Germany, began experimenting with gliders and ornithopters in the early 1890s. In 1896, he demonstrated his flapping wing flying machine at Berlin. The Stentzel machine had cambered bird-like wings of 6.5 m. wingspan and a rounded cruciform tail. It was powered by a carbonic acid engine mounted forward and below the wings. The flying machine ran along a horizontal wire, off which it lifted when in motion. The machine achieved a speed of 4.5 m/s.
