Jean Jacques Raimond Jr. (13 April 1903, inThe Hague – 3 December 1961)[1] was a Dutchastronomer.
Raimond was the son of Jean Jacques Raimond Sr., furniture maker in The Hague, and Tetje van der Werf. He studied astronomy at the universities ofLeiden andGroningen. He obtained his PhD at the latter as a student ofJacobus Kapteyn, defending the dissertationThe Coefficient of Differential Galactic Absorption.
He became the director of theZeiss Planetarium in The Hague at its opening in 1934. This was the first planetarium installed outside Germany. Here he had a strong influence on the popularization of astronomy. In 1944 he became the president of the 'Nederlandse Vereniging voor Weer- en Sterrenkunde' (NVWS, Netherlands Association for Meteorology and Astronomy) after serving as a board member. From 1938 until his death in 1961, he published annual issues of the popular series 'Sterrengids', an astronomical almanac.[2]
The asteroid1450 Raimonda is named after him, as is the craterRaimond on theMoon. His son Ernst became a radio astronomer.
In 1955 a local Dutch astronomy society was named after him. This society still exists albeit under a different name:Triangulum. Recently it celebrated its 50th year of existence.
