About Jacob Ellehammer
Jacob Christian Hansen-Ellehammer was a Danish inventor and aviation pioneer. He obtained a total of 59 Danish patents and worked with many different things, including amusement machines, Tivoli boats, egg openers, cleavers for pig slaughterhouses, engines in countless shades, motorcycles, cars, alternative energy and fire-fighting equipment. He was also among the first in Europe to fly an airplane. Ellehammer wanted to be the first in Europe to fly and in 1905 built a machine which he called an "airship". The first engine was judged too weak, so Ellehammer built a new engine with 18 hp, which was used for the flight tests from August 1906. The father and his two brothers, Christian and Henrik, took part in the drainage of Vålse Vig using an invented water lift which was driven by a Dutch windmill.
