Otto August Rosenberger

Otto August Rosenberger ( born August 10, 1800 Tukums in Latvia, † January 23, 1890 in Halle ( Saale) ) was a German astronomer.

He moved in 1811 with his father, a doctor from Latvia to Königsberg on. He studied 1819-25 at the university astronomy under Friedrich Wilhelm Bessel, whose assistant he was for several years. In 1826 he was an associate professor of applied mathematics and Observer at the Observatory at the University of Halle, where he was in 1831 appointed professor. Until 1879 he lectured. He died on 23 January 1890.

As the condition of Hall 's observatory did not favor astronomical observations, remained Rosenberger's astronomical activities in hall next to his lectures limited to computational work, one of which ( in Volume 6 of the " Astronomische Nachrichten " ) the Lappish degree measurement, the other ( in Vol 8-13 of the " Astronomische Nachrichten " ) refers to Halley 's Comet. Especially the latter, according to Bessel's judgment the most careful and successful path calculation for this comet, Rosenberger's name has been known in other circles.

In 1837 he was awarded the Gold Medal of the Royal Astronomical Society. The lunar crater Rosenberger is named after him.

Rosenberger's son was the physician Georg August Wilhelm Julius Rosenberg.
