Ernst Christoph Friedrich Knorre
Ernst Christoph Friedrich Knorre (born December 11, 1759 in Haldensleben , † December 1, 1810 in Dorpat ) was a German astronomer and mathematician.
Life
Knorre was after studying Protestant theology in Halle first tutor at a bookstore Gebauer in Halle and from 1789 in Tartu as a teacher and later director at the Higher School for Girls, where his older brother already, he replaced as director on as the Narva went . He was also organist at the St. Johannis Church. In 1803 he became an associate professor of mathematics at the newly founded University of Dorpat and an observer at the newly founded observatory Dorpat , which, however, was not yet fully completed when he died prematurely.
Knorre was an autodidact as an astronomer and even before the observatory opened, he determined the latitude of Dorpat with instruments he had built himself, which he later continued in other places in Livonia . He was less successful in his length determinations; Friedrich Georg Wilhelm Struve was only able to use one of his observations after his death. He did not get along well with the astronomer Johann Wilhelm Andreas Pfaff , who had been a professor of mathematics since 1803: He mistrusted his abilities and this kept him away from the observatory until Pfaff left in 1809. He published astronomical observations in Bode's Astronomical Yearbook.
He had been married to Friederike Senff since 1790 and after her death in 1791 he married Sophie Senff in Dorpat in 1793, both sisters of Karl August Senff and daughters of Karl Friedrich Senf . His son Karl Adolph (1799–1873) became a doctor well known in the Baltic States, his son Karl Friedrich Knorre (1801–1883) became an astronomer and director of the Nikolajew observatory . His son Viktor Knorre (1840-1919) was also a well-known astronomer.
In 2010 the asteroid (14339) Knorre was named after him, his grandson Viktor and his son Karl Friedrich.
