On this day, Nazis murdered Joop Westerweel, a Righteous Among the Nations - a non-Jewish ally who had a mission to help Jewish people during the Holocaust. He was raised in a Christian household and grew up with the values of pacifism. After expulsion from the Dutch East Indies for refusing to join the army, he became a teacher at a progressive school in Bilthoven, a small village in the Netherlands. While teaching, Westerweel worked with Jewish refugee children who came to Holland in the 1930s to escape the Nazi regime. In 1940, he moved to Rotterdam and became the principal of a Montessori school. He met a group of Jewish pioneers who wanted to learn about agriculture before moving to Israel. When the Nazis started to round up Jews more rapidly, Westerweel tried to hide his Jewish friends. But, as the Nazis would typically find hidden Jews, he came up with an escape route for the Jews to get to Spain, then get to Israel. Joop and his group smuggled 150 to 200 Jewish people during the Second World War. On March 14, 1944, the Nazis arrested Joop while he was trying to smuggle out two Jewish women; They sent Joop Westerweel to the Vught concentration camp. On June 16, 1964, Joop and his wife, Wilhelmina, were recognized as Righteous Among the Nations by Yad Vashem for their efforts to save Jews during the Holocaust.
