Viktor Karlovich Knorre (ロシア語:Виктор Карлович Кнорре)(4 October 1840 – 25 August 1919) was a Russian astronomer of German ethnic origin. He worked in Nikolaev, Pulkovo and Berlin and is best known for having discovered 158 Koronis and three other minor planets. Knorre's father, Karl Friedrich Knorre, and grandfather, Ernst Friedrich Knorre, were also prominent astronomers. Recently NASA named an asteroid in honor of the three generations of Knorre astronomers.〔(【引用サイトリンク】title=Asteroid named after the three generations of Knorre Astronomers )〕 ==Biography and family background== Knorre was born into a three-generation astronomer family. His grandfather, Ernst Friedrich Knorre (1759–1810), had moved from Germany to Dorpat (now Tartu, Estonia) where he worked (1803–10) as ''Observator'' for the Dorpat observatory (opened in 1802) and professor of Mathematics at the University of Dorpat. Victor Knorre's father, Karl Friedrich Knorre (1801–1883),〔 set up and was director of the Nikolayev Astronomical Observatory starting in 1827. Viktor was born the fifth of fifteen children in Nikolayev (now Mykolayiv, Ukraine). He moved to Berlin in 1862 to study astronomy with Wilhelm Julius Foerster. He worked at Pulkovo Observatory in 1867 as an astronomical calculator and then at Berlin Observatory, where his father moved circa 1871. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Viktor Knorre」の詳細全文を読む スポンサード リンク
