Karl Ludwig Hencke

Hencke was born in Driesen, Brandenburg (now Drezdenko, Poland).

He discovered two asteroids from his private observatory at #9, Kietz (now #43, Kietzerstraße), Driesen. The first, 5 Astraea, is notable for being the first asteroid discovered after the long gap that followed the last of the original four, 4 Vesta, which was discovered in 1807. Other astronomers had abandoned their searches for more asteroids, convinced that there were only four. However, Hencke began searching in 1830, and fifteen years later met with success.

He died at in Marienwerder (now Kwidzyn), then part of Prussia.

The asteroid 2005 Hencke is named in his honour.
