Johan Maurits Mohr
Astronomer
1716 – 1775
Who was Johan Maurits Mohr?
Johan Maurits Mohr was a Dutch-German pastor who studied at Groningen University from 1733 and settled in Batavia in 1737. Mohr's greatest passion was in astronomy but he was also keenly interested in meteorology and in vulcanology.
In 1765 Mohr built a large private observatory in Batavia that was equipped with the best astronomical instruments of his time. His observatory, which had cost him a small fortune, was visited and praised by Louis Antoine de Bougainville and James Cook.
Mohr observed the Venus transits of 6 June 1761 and 3 June 1769 and the Mercury transit of 10 November 1769. He also made meteorological observations and measurements of the magnetic declination at Batavia.
After Mohr's death his observatory was damaged by an earthquake in 1780, fell into ruin and was demolished in 1812.
The minor planet 5494 Johanmohr is named in his honour.
