A memorial has been placed at the cemetery of Waddinxveen, The Netherlands.

On behalf of Anna (Anneke), Michiel, Inge, Lotte, Sam, Céline and myself I would like to thank all people that paid us a visit at the ceremony in Rotterdam. You all helped us to make this a memorable and worthy goodbye to our dear husband, father, father in law and grandfather.

To all of you who shared their intimate thoughts and feelings, thank you very much. We have read, re-read and appreciated each one of these and will cherish these as an additional good memory.
