J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. Sjoerd Hardeman (1982-2011) was a member of the Jongeren WerkGroep voor sterrenkunde (Dutch Youth Association for astronomy). He was a leader on several astronomy holiday camps and gave many presentations on astronomy. He died from leukemia shortly before defending his PhD.
