Hendricus Gerardus van de Sande Bakhuyzen

Hendricus Gerardus van de Sande Bakhuyzen , also: Hendrik Gerard van de Sande Bakhuijzen , (born April 2, 1838 in The Hague , † January 8, 1923 in Leiden ) was a Dutch astronomer. He was mainly active in positional astronomy and the observation of planets and was one of the first to investigate systematic measurement errors in detail .

Life

Hendricus Gerardus was born the son of the landscape painter Hendrik van de Sande Bakhuyzen (* January 2, 1795 in The Hague; † December 12, 1860 there) and his wife Sophia Wilhelmine Kiehl (* December 23, 1804 Oranienstein Castle; † 1881). After attending grammar school in The Hague, from 1855 he attended the civil polytechnic engineering school in Delft . Here he received his engineering degree on June 1, 1859, and enrolled on March 2, 1860 at the University of Leiden , where he studied mathematics and physics. His formative teachers were Gideon Jan Verdam , Pieter Leonard Rijke and Frederik Kaiser . On April 21, 1863 he received his doctorate with a thesis on the curvature of the median circle, under the title Over den invloed de buiging op de hoogten van hemellichten met den meridiaanmeter bepaald at the mathematics and physics faculty for a doctorate in philosophy.

In 1862 he had already worked as a teacher at the grammar school in The Hague, had taught at the HBS Utrecht for a year from 1866 and became a professor at the Polytechnic in Delft in 1867. After he had become a member of the Royal Netherlands Academy of Sciences on May 11, 1872 , he was appointed professor of astronomy at the University of Leiden on September 3, 1872. He took on this task on December 20, 1872 with the inaugural speech De methode, welke thans bij de beoefening d. asterrenkunde must have been followed and became director of the Leiden observatory . As a teaching staff at the Leiden University he also took part in the organizational tasks of the same and was rector of the Alma Mater in 1886/87 . He retired on July 27, 1908 and retired on September 21, 1908.

Memberships

Sande Bakhuyzen was a member of many learned societies. He was a member of the Astronomical Society in Leipzig (founded in 1844), in 1894 a corresponding member of the Bureau des Longitudes, a member of the International Association of Geodesy and an employee of the Carte du Ciel star atlas . From 1900 he was the permanent secretary of earth measurements and president of the Royal Netherlands Academy of Sciences . In 1896 he became a corresponding member of the Académie des Sciences .

Honors

family

On August 19, 1869, Sande Bakhuyzen married Geertruida van Vollenhoven (born December 19, 1840 in Rotterdam; † January 23, 1910 in Leiden), the daughter of the businessman Adriaan van Vollenhoven (born January 23, 1801 in Rotterdam; † 25. June 1871 ibid) and his wife Rudolfina Maria Louisa Baelde (born November 6, 1809 in Rotterdam; † November 18, 1848 ibid). There are children from this marriage. We know of these:

Sande Bakhuyzen had earned a reputation as an exact position determiner of stars during his time in office . For this purpose, he had written various papers for domestic and foreign specialist journals and magazines of his time. In addition, some of his own works have also appeared. We know of these:
