(11427) Willemkolff is an asteroid of the main belt that was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The asteroid was named on September 26, 2007 after the Dutch internist Willem Kolff (1911–2009), who had the first drum dialyzer built in 1942 and thus achieved his first healing success in September 1945 after several failures.
