Karl Ludwig Harding

Karl Ludwig Harding (born September 29, 1765 in Lauenburg , † August 31, 1834 in Göttingen ) was a German astronomer .

Life

Harding was the son of Pastor Carl Ludwig Harding . He studied theology in Göttingen and taught in Lilienthal near Bremen as a private tutor to the son of the Oberamtmann Johann Hieronymus Schroeter , who had founded the Lilienthal observatory .

From 1796 Harding worked as an "inspector" at the observatory and in 1800 was appointed an observator . On September 1, 1804, it was from there that he discovered Juno , the third asteroid or planetoid of the solar system .

In 1805, Harding received a call as associate professor for astronomy at the University of Göttingen , before becoming a full professor in 1812. He made observations on comets , gas nebulas and variable stars . He discovered the variable stars R Virginis, R Aquarii , R Serpentis and S Serpentis. With the Atlas novus coelestis he published the first star atlas that did not contain any allegorical representations that would interfere with practical work.

For the Berlin Academic Star Maps , a project of the Royal Prussian Academy of Sciences , he supplied the first sheet in 1826 and another in 1833.

In 1803 he was elected a corresponding member and in 1806 a full member of the Göttingen Academy of Sciences . Since November 1810 he was a corresponding member of the Académie des sciences .

Karl Ludwig Harding died on August 31, 1834 in Göttingen. In recognition of his achievements, the asteroid (2003) Harding and the lunar crater Harding were named after him.
