Karl Theodor Robert Luther (16 April 1822, Świdnica – 15 February 1900 Düsseldorf), normally published as Robert Luther, was a German astronomer. While working at the Bilk Observatory in Düsseldorf, Germany, he searched for asteroids and discovered 24 of them between 1852 and 1890.[1][2] Seven times Lalande Prize winner.
Biography
[edit]Karl Theodor Robert Luther was born on 16 April 1822 to August Luther and Wilhelmine von Ende. He was home schooled and studied in the local high school. In 1841, he moved to Breslau where he studied until 1843.[3]
In 1843 Luther moved to Berlin to study astronomy. He was a student of Johann Franz Encke and helped him in his astronomical calculations and creating the astronomical almanac. In 1850 he became a second observer. In 1851, Franz Brünnow invited Luther to the Düsseldorf-Bilk Observatory to become a director of the observatory after him.[3]
Luther married Caroline (nee Marker) and they had one son, William. Luther died in 1900 after a short illness in Düsseldorf.[3]
Discoveries
[edit]Luther discovered 24 asteroids between 1852 and 1890.[1][2]
Two of his discoveries are now known to have unusual properties: 90 Antiope, a binary asteroid with equal components, and the extremely slow-rotating 288 Glauke.
