Moritz Ludwig George Wichmann

Moritz Ludwig Georg Wichmann ( born 14 September 1821 in Celle, † February 7, 1859 in Königsberg ( Prussia) ) was a German astronomer.

After visiting the Ernestinums in Celle Wichmann studied in Göttingen in Gauss. There he received in 1843 an academic prize for a work in which he dealt with a problem of the spherical geometry.

In 1844 he was appointed by Friedrich Wilhelm Bessel as an assistant and an observer in the observatory in Königsberg, where he habilitated in 1830 with a thesis on the parallax of the star Groombridge. About this parallax, there was a violent, out with some polemic confrontation with the astronomers of the main Russian Pulkovo Observatory, which still should last for many years. Except put on this subject Wichmann before work on the newly discovered planetoid, the libration of the moon and the prominences of the sun.

Named after him were 1935, the lunar crater Wichmann and in 1953 discovered asteroid ( 7103 ) Wichmann.
