Ernst Friedrich Knorre

Ernst Christoph Friedrich Knorre (11 December 1759 – 1 December 1810) was a German-born astronomer who lived and worked in present-day Estonia as a founding professor of mathematics at the Universität Dorpat and chief observator for the Dorpat Observatory. His son Karl Friedrich Knorre and grandson Viktor Knorre were also notable astronomers. Recently NASA named an asteroid in honor of the three generations of Knorre astronomers.
