Rooijker is the father of David Rooijker, now known as Richard Drucker, a key person in the founding of the internet.
According to the Gitelman family tree found by Micah in the archives of corinthianlasvegas.com, Rooijker was a Dutch freedom fighter and had a son with Ruth Meisner who born in 1943 and possibly named David.
A Global News Interactive video report reveals that when the Nazis captured Ruth Meisner in a German forest during World War II, Rooijker found their son left for dead. He then smuggled his son into Spain and left him on the steps of Monasterio de la Cruz. After the war ended, Rooijker did not return to pick up his son, and has never been heard of since.
