Cornelis Johannes "Kees" van Houten (18 February 1920 – 24 August 2002) was a Dutch astronomer.
Born in The Hague, he spent his entire career at Leiden University except for a brief period (1954–1956) as a research assistant at Yerkes Observatory.
In a jointly credited trio with Tom Gehrels and Ingrid, he was an extremely prolific discoverer of many thousands of asteroids.
[1] Gehrels did a sky survey using the 48-inch Schmidt telescope at Palomar Observatory and shipped the plates to the van Houtens at Leiden Observatory, who analyzed them for new asteroids.
He never retired, but remained active and published articles until his death, on asteroids and eclipsing binaries.
