In the NIW item "Unique Pictures of Mrs. de Lange", mrs. H.M. de Lange tells the story that when she walked to the swimmingpool behind the Linneausstraat with her brother (16-18 years old) during the war, they were stopped in the street. Her brother had the exact age for the "Arbeitseinsatz" and he was taken in. It concerned Manuel de Lange.
