Jacob Heinrich Wilhelm Lehmann

Jacob Heinrich Wilhelm Lehmann ( born January 3, 1800, Potsdam, † July 17, 1863 in Spandau ) was a German astronomer.

After studying theology and mathematics in Halle, Berlin and Göttingen with subsequent promotion was Lehmann Subrektor on Joachimsthalerstrasse Gymnasium in Berlin and the following year vice-principal at the high school in Greifswald. In the fall of 1828, he gave up this position again in order to devote himself first astronomical work. In 1832 he became a preacher in the Brandenburg villages Derwitz and Krielow. From 1843, he lived as a private scholar in Berlin, Potsdam and Spandau.

His astronomical work had a focus in the comet astronomy, which was also the subject of his dissertation. In 1835 he published a study on the path of Halley 's comet, and in 1842 a work on eclipses and especially the upcoming solar eclipse of July 8, 1842. The total already printed edition of this book burned, however, the Hamburg city fire of May 1842 so that a second edition after the event could appear. A large planned celestial mechanics work on the planetary motions, he could not finish. For a long time lung suffering, he died in 1863 of a hemorrhage.

The lunar crater Lehmann is named after him.
