Jacob Heinrich Wilhelm Lehmann
Jacob Heinrich Wilhelm Lehmann (born January 3, 1800 in Potsdam , † July 17, 1863 in Spandau ) was a German astronomer.
After studying theology and mathematics in Halle , Berlin and Göttingen with subsequent doctorate, Lehmann became sub-rector at the Joachimsthaler Gymnasium in Berlin and in the following year deputy director at the grammar school in Greifswald . In the autumn of 1828 he gave up this position again to devote himself to astronomical work. Felix Eberty took private mathematics lessons from him in 1833. In 1832 he became a preacher in the Brandenburg villages of Derwitz and Krielow . From 1843 he lived as a private scholar in Berlin, Potsdam and Spandau.
His astronomical work had a focus on comet astronomy , which was also the subject of his dissertation. In 1835 he published a study on the orbit of Halley's comet and in 1842 a paper on solar eclipses and specifically the impending solar eclipse of July 8, 1842 . However, the entire already printed edition of this book burned in the Hamburg city fire of May 1842, so that a second edition could only appear after the event. He could no longer complete a large planned celestial mechanical work on the planetary movements. Having had a lung for a long time, he died of a hemorrhage in 1863 .
The lunar crater Lehmann is named after him.
