The first design of Adolphe-Étienne Lachassagne was a 1912-1913 tandem wing monoplane. As Lachassagne had no funds to acquire a new and powerful engine he had to do with second hand engines. Lachassagne started to study a new aeroplane with tandem wings. The AL-2 airplane was never built in full size, only as a model.

Lachassagne was creative inventor and kept developing and building variable wing profile aircraft at least up to WW2. He also tried to develop a small affordable “peoples airplane”.

Slovakian aviation pioneer (1883-1974)

Frederick Kuhnert of New Jersey established the Kuhnert Aerial Construction Company in order to “manufacture flying machines”. The $100,000-valued company’s directors were Frederick Kuhnert, Matthew Andronico and Lester Gilbert. In 1910, Kuhnert bought 20 acres of land in the Hackensack Meadowlands to use as an aerodrome where he built a passenger airplane that could hold 14 people. Called Kuhnert’s Ferryboat, it, along with his aerodrome, was destroyed by a tornado in 1912 before it could make its first flight. Prior to the tornado, the Kuhnert Aerodrome hosted weekly aerial demonstrations.

Wilhelm Krumsiek was a well-known German aviation pioneer, particularly for the 1912-1914 years.

One machine flew in 1909, and crashed sometimes later.

After having built a second airplane, he became in 1912 chef pilot at the “Zentrale für Aviatik Karl Caspar” (Hansa), and flew with success at a number of competitions (Prinz-Heinrich Flug 1913, duration world record for monoplanes, etc…)
