Jacob Ellehammer

Jacob Ellehammer

Jacob Christian Hansen Ellehammer (June 14 1871May 20 1946) was a Danish watchmaker and inventor born in Bakkebølle, Denmark. He is remembered chiefly for his contributions to powered flight.

Following the end of his apprenticeship as a watchmaker he moved to Copenhagen where he worked as an electronics mechanic before establishing his own company in 1898. In the beginning he produced cigarette machines, beverage machines and other electronic machinery. In 1904 he produced his first motorcycle, the Elleham motorcycle.

In 1905, he constructed a monoplane, and in the following year a "semi-biplane". In this latter machine, he made a tethered flight on 12 September 1906, becoming the second European to make a powered flight (after Traian Vuia).

Ellehammer's later inventions included a successful triplane and helicopter.
