Paul Haenlein
Paul Haenlein was an aero inventor who filed patents from Mainz in the 1870s. He appears to have filed patents from Frauenfeld, Switzerland in the 1890s, though it is conceivable that this is a different inventor with the same name.
On 13 December 1872, Haenlein flew, from from the city of Brno, Moravia, a vessel equipped with a Lenoir engine which fed upon gas contained in the balloon.[1][2] His ship reportedly flew at a speed of 19 km/h.[3]
"He was the first to create a dirigible airship which was powered by an internal combustion engine."[4]
"In 1872 Haenlein obtained a U.S. patent (No. 130 915) to use the otherwise wasted gas in the dirigible's engines."[4]

Haenlien died before or in 1909. His wife Mathilde sent a letter to Moedebeck at that time, saying so. It's the last letter in the Lilienthal museum collection. She wrote from Wien, a new location so far as we can tell.[1]
