The Minor Planet Center attributes the discovery of 4,641 numbered minor planets to the collaborative trio of Ingrid van Houten-Groeneveld, her husband Cornelis Johannes van Houten, and Tom Gehrels. Operating out of the Netherlands, her systematic analysis of photographic plates expanded the catalog of the solar system significantly during the twentieth century.
Early Life and Education
Born in 1921 in Berlin, Ingrid van Houten-Groeneveld pursued her academic training at Heidelberg University. Her scientific career eventually brought her to the Netherlands, where she held citizenship and established her professional base of operations at Leiden University.

Her most significant contributions involved the Palomar–Leiden survey. In this project, Tom Gehrels utilized the 48-inch Schmidt telescope at the Palomar Observatory to capture imagery of the night sky. He then transferred these photographic plates to Leiden, where van Houten-Groeneveld and her husband meticulously reviewed the data to identify previously unknown asteroids.
Research and Legacy
Beyond her extensive work in asteroid detection, she published research on cometary orbits, light curves, and the photometry of variable stars. The asteroid 1674 Groeneveld, initially discovered by Karl Reinmuth and independently sighted by Yrjö Väisälä in 1938, was named in her honor. She remained an active member of the International Astronomical Union throughout her career until her death in 2015 in Oegstgeest.
