14339 Knorre           Discovered 1983 Apr. 10 by L. I. Chernykh at the Crimean Astrophysical Observatory.
Ernest Khristov Knorre (1759-1810) was the first astronomer at Tartu University. His son Karl Khristov Knorre (1801-1883) was the first director of the naval Nikolaev Observatory. Victor Karlovich Knorre (1840-1919) worked in Nikolaev, Pulkovo and Berlin and discovered (158) Koronis and three other minor planets.
