Discovered over 3,000 asteroids and comets, earning her the title "First Lady of Asteroids" for her groundbreaking contributions to astronomy.
Ingrid van HoutenGroeneveld is renowned for being part of a trio that discovered an astonishing 4,641 numbered minor planets, earning her a permanent place in the annals of astronomy. Alongside her husband Cornelis Johannes van Houten and Tom Gehrels, she formed a dream team that revolutionized the field of asteroid discovery.
Ingrid van HoutenGroeneveld was born on October 21, 1921, in the Netherlands. Her fascination with the stars led her to pursue a career in astronomy, and she went on to make significant contributions to the field.
The Palomar-Leiden survey, a collaborative effort between Palomar Observatory and Leiden Observatory, was the platform for Ingrid's remarkable discoveries. Tom Gehrels would capture images using the 48-inch Schmidt telescope at Palomar, and then send the photographic plates to the van Houtens at Leiden for analysis. This partnership led to the discovery of several thousand asteroids, cementing Ingrid's status as a leading astronomer.
Ingrid's research was not limited to asteroid hunting. She published several papers on photometric studies of asteroids, including "Lichtelektrische Beobachtungen ausgewählter veränderlicher Sterne" (1947) and "Photometric studies of asteroids. I" (1954), co-authored with Gerard P. Kuiper. Her work greatly advanced the understanding of asteroids and their behavior.
In recognition of her contributions, the Themistian main-belt asteroid 1674 Groeneveld was named in her honor. This distinction is a testament to her groundbreaking work in astronomy.
Ingrid van HoutenGroeneveld's tireless efforts have inspired generations of astronomers and asteroid hunters. Her discoveries have greatly expanded our knowledge of the solar system, and her legacy continues to influence the field of astronomy.
Ingrid van HoutenGroeneveld passed away on March 30, 2015, at the age of 93, but her remarkable achievements will continue to inspire and guide astronomers for years to come.
