Anton Karl Thraen
(January 17, 1843 in Holungen
– February 18, 1902 in Dingelstädt
) was a German astronomer
and named two minor planets
, 442 Eichsfeldia
and 443 Photographica
Thraen was born on January 17, 1843 in Holungen, where he attended the elementary school at that time. In 1863, he completed his schooling in Heiligenstadt
and went to Westfaeliche Wilhelms University
(1863–66), and the University of Paderborn
(1866–68) and learned theology. Already in Munster, he also knew mathematical
lectures and helped at the observatory.
From 1883 up to his death, he worked as a minister in Dingelstädt. Here, he organised charitable collections for the development of the hospital
and the parish church. By night he often observed the sky with his telescope
, particularly working on the orbits of comets
and minor planets, publishing his results in international technical periodicals.
Despite going blind
in his left eye
, this work was continued. He observed the short-period Comet III (Wolf) in 1884-85 with 950 observations and in 1891-92 with 681 observations, and calculated its orbit to forecast the third return. Thraen also discovered several new asteroids, which received the name "Eichsfeldia" and the name "Photographica" from Professor Wolf.
Thraen was honoured by the Prussian state
in 1900 with the award of the Roten-Adlerordens, IV class. Only in 1902 at a conference in Göttingen
did he become personally... Read More
