As a student several years ago I invited Pim to come give a talk at a student life sciences symposium in the Netherlands. To my great delight he generously agreed to fly over to do this. As a fellow scientist (and Dutchman) he was and will continue to be an inspiring example of somebody living his dream while making great contributions to science. My sincere sympathy and condolences to Pim's family and friends for this way too early loss..
Pim was original, critical, determined yet excedengly nice person. A rather rare combination of qualities. He will be missed.
The entire scientific community is saddened by the loss of one of our most creative and innovative scientists---I personally will miss his boundless energy and his enthusiasm about what is possible
Pim was a wonderful man, and developed science that is pervasive. He changed the world.
