Carl Wanke of Coswig/Anhalt, Germany, started in 1912 to build aircraft. He set up a small workshop and with help of local carpenters, technicians and other enthusiasts he constructed his first aircraft. That was said to have been projected as monoplane, but it was only able to move some 30 metres on the ground. Then Wanke rebuilt the wings and apparently created the biplane shown above. It was tested with some hops, but after a somersault during the first public trial flight it was wrecked.
