Jacob Ellehammer (1871-1946)
Jacob Christian Hansen-Ellehammer (14 June 1871 – 20 May 1946) was a Danish watchmaker and inventor born in Bakkebølle, Denmark. He is remembered chiefly for his contributions to powered flight. His successful triplane design is shown here, with which he finally achieved longer distance flying, but it was still just many times around a pole, to which the uncontrolled plane was tethered.
