Why Is Sidney van den Bergh Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Sidney Van den Bergh, OC, FRS is a retired Dutch-Canadian astronomer. He showed an interest in science from an early age, learning to read with books on astronomy. In addition to being interested in astronomy. He also liked geology and archeology. His parents got him science books, a telescope, and a microscope, although they wished him to pursue a more practical career and only follow astronomy as a hobby. He went to Leiden University in the Netherlands from 1947 to 1948. He then attended Princeton University on scholarship where he received his A.B. in 1950. In December 1950, he was living in Columbus, Ohio and evidencing an interest in Astronomy. He obtained an MSc from Ohio State University and a Dr. rer. nat. from the University of Göttingen .
