Life

Oudemans was the son of the poet, teacher and philologist Anthonie Cornelis Oudemans (born May 11, 1798 in Dordrecht, † October 1, 1874 in Nijmegen) and his married Jacoba Adriana Hammecher on February 23, 1825 (born March 14, 1800 in Rotterdam; † November 16, 1862 in Arnhem). The parents' marriage resulted in several children, with his older brother Corneille Antoine Jean Abraham Oudemans also becoming an important botanist. After initial private lessons, Oudemans enrolled at the University of Leiden on September 14, 1844 . Here he concentrated on astronomical research, with Frederik Kaiser becoming his formative teacher, under whom he received his doctorate in natural philosophy on October 2, 1852 with the astronomical treatise Observationes, ope instrumenti transitorii portabilis institutas. From January 1, 1847 to September 30, 1853 he was the second teacher of mathematics at the Gymnasium in Leiden and on April 1, 1853 he became an observator at the Leiden observatory . As such, he published articles in the scientific journals of the Astronomical News, the journals of the Academy of Sciences and in the Algem. Konst en Letterbode. Later also in the Astronomical Journal and the Monthly Notices of the Royals Astronomical Society.

On April 27, 1856 he was appointed associate professor at the University of Utrecht . He took on this task on June 13, 1856 with the introductory speech Over de jongste vorderingen der sterrenkunde, voornamelijk in de laatste vijfentwintig jaren and became director of the observatory there for the first time. But his research interests were also geography . In 1857 he traveled to the Dutch East Indies as chief engineer and head of the geographic service , where he worked for 18 years and directed extensive geodetic operations. He published his work on the triangulation of the island of Java in six volumes. On December 9, 1874, under difficult weather conditions, he and his expedition members observed the transit of Venus from the island of Réunion . From January 20, 1876 until his retirement on September 20, 1898 he was again professor of astronomy and director of the observatory at the University of Utrecht. In 1889 he published a star map. In 1889/90 he was the rector of the university . Besides a number of geodetic and astronomical treatises he published the 4th edition of Kaiser's popular work De Sterrenhemel (Deventer 1884-88). Oudemans was on April 6, 1855 member of the Royal Dutch Academy of Sciences in Amsterdam, on November 9, 1883 member of the Royal Astronomical Society and May 6, 1901 member of the Académie des Sciences in Paris. He was a Knight of the Order of the Dutch Lion and the Oudemans Crater on Mars was named in his honor. In 1898 he took legal retirement, but continued to work on astronomical and biographical topics until his death.
