Marietta Moskin, née Duschnitz, was born to a Jewish family in Vienna, Austria. Her family went to the Netherlands to escape Nazi persecution, and she went to school in Amsterdam until 1940, when they were arrested and sent to concentration camps. They survived and emigrated to the USA in 1946. She earned a BA from Barnard College and an MA in economics from the University of Wisconsin, and worked as an economist for General Motors. Later, she became a prolific children's book author, publishing 16 books plus short stories and translations. Her novel I Am Rosemarie, based on her experiences in the Holocaust, is considered a classic and is read in schools throughout the USA and Europe.
