Ada van Keulen

Aleida Mathilda (Ada) van Keulen (13 January 1920, Aalsmeer – 25 January 2010, Laren, North Holland) was a Dutch woman who took part in the resistance during World War II.

Van Keulen headed an illegal boy scout group in Hilversum, the Heidepark Group, which carried out work for the resistance. She was also a courier. On June 13, 1944, she was betrayed and arrested together with 27 other resistance fighters in Amsterdam. Among others, they included Jo Hessels, Hendrik van Wilgenburg, and Joukje Grandia-Smits, all of whom were imprisoned. Of the 27, only seven survived the war.

She was sent to Herzogenbusch concentration camp and in September 1944 deported to Ravensbrück. In October, she was transferred to Dachau, where she was employed in the Agfa-Commando.

On April 30, 1945, van Keulen was freed by the Americans during the Wolfratshausen evacuation march.
