Stock Photo - Prince Bernhard’s original Nazi party membership card found. He was married to dutch Queen Juliana. Grandfather of King Willem Alexander. Despite his categorical denials, irrefutable proof of the late prince Bernhard’s membership of the Nazi party NSDAP has been found in his private archives. Flip Maarschalkerweerd, former director of the royal archives found the original membership card when making an inventory of the prince’s private papers some years before his retirement in 2019. Maarschalkerweerd makes the revelation in his book De Achterblijvers (Those who stayed behind) which is to be published on Wednesday. Prince Bernhard had always denied he was a member of Hitler’s national socialist party, despite a copy of his membership discovered in the United States in the 1990s. Letters discussing the termination of his membership in 1936, the year in which he became engaged to the then princess Juliana, have also been found. *** Local Caption *** 00107257.
