Ingrid van Houten-Groeneveld ((:ˈɪŋɡrɪt fɑn ˈɦʌutəŋ ˈɣrunəˌvɛlt);〔In isolation, ''van'' and ''Houten'' are pronounced (:vɑn) and (:ˈɦʌutən), respectively.〕 21 October 1921 – 30 March 2015) was a Dutch astronomer. In a jointly-credited trio with Tom Gehrels and her husband Cornelis Johannes van Houten, she was the discoverer of many thousands of asteroids. In the Palomar–Leiden survey, Gehrels took the images using the 48-inch Schmidt telescope at Palomar Observatory and shipped the photographic plates to the van Houtens at Leiden Observatory, who analyzed them for new asteroids. The trio are jointly credited with several thousand asteroid discoveries. Van Houten-Groeneveld died on 30 March 2015, at the age of 93, in Oegstgeest, Netherlands.〔 (Leidse sterrenkundige Ingrid van Houten overleden (21 oktober 1921-30 maart 2015) ), Astronomie.nl, 2015.
