Cornelis Gijsbert Gerrit Jan van Steenis (31 October 1901 – 14 May 1986) was a Dutch botanist.

Besides his expeditions in the Malay region, he also traveled in Australia and New Zealand.
Balthasar van der Pol (27 January 1889 – 6 October 1959) was a Dutch physicist.
Albertus (Albert) Antonie Nijland (30 October 1868 – 18 August 1936) was a Dutch astronomer. He was professor of astronomy at the Rijksuniversiteit Utrecht, and served as director of the Sterrewacht Sonnenborgh (now the Sterrekundig Instituut) of the university.
Nijland was born in Utrecht. In 1901 he participated in a Dutch solar eclipse expedition to Karang Sago, Sumatra.
He was noted for his observations of variable stars, and published a number of papers on the subject in Astronomische Nachrichten, and elsewhere, from 1917 until 1936. He proposed naming variable stars in each constellation using a simple numbering system beginning with V1, V2, ... and so forth. However the double-letter system starting with RR was already in
widespread use. As a result, variable stars after QZ were numbered according to Nijland's system beginning with V335.
In 1923 Nijland became member of the Royal Netherlands Academy of Arts and Sciences.The crater Nijland on the Moon is named after him.
Marcel Gilles Jozef Minnaert (12 February 1893 – 26 October 1970) was a Belgian-Dutch astronomer. He was born in Bruges and died in Utrecht.
