Florentine Rost van Tonningen

Florentine Sophie Rost van Tonningen (née Heubel; 14 November 1914 – 24 March 2007) was the wife of Meinoud Marinus Rost von Tonningen, the second leader of the National Socialist Movement in the Netherlands (NSB) and President of the National Bank during the German occupation (1941–1945). Because she continued to support and propagate the ideals of Nazism after World War II and the death of her husband, she became known in the Netherlands as the "Black Widow".
