Henriette Roosenburg (1916-1972), known as 'Zip', was part of the Dutch resistance during World War II, collecting news for the underground press and helping maintain an escape route for crashed Allied pilots. After being arrested in 1944 and condemned to death, she survived internment in a Gestapo prison in Germany before being liberated by the Russian army in May 1945. After the war, she emigrated to the United States, and started to work for Life Magazine. She wrote the first draft of what would later become The Walls Came Tumbling Down for The New Yorker.
