The Dutch-Paris Line created and led by Weidner became one of the largest and most successful nonviolent rescue operations of the entire war. It saved the lives of approximately three thousand people faced with imprisonment and extermination. The underground network of safe houses grew to nearly 300 members operating with forged documents across four borders, two mountain ranges, and six occupied zones, each requiring identity papers and travel passes. The Dutch-Paris Line also relayed microfilm and intelligence to the Allies and resistance groups. Near the end of the war, the Nazis managed to infiltrate the Line. Sixty-five Dutch-Paris rescuers were arrested and 14 died in concentration camps. The story not only of Weidner but of the Line in its entirety is told in detail for the first time in Megan Koreman’s book, The Escape Line (Oxford University Press, 2018). Koreman’s research was made possible through grants from the John Weidner Foundation for Altruism.
