Irene Hasenberg Butter (* 1930) fled Berlin to the Netherlands with her family in 1938 as a child. Among the other displaced German children in her friend group was Anne Frank. During a raid in Amsterdam in June 1943, the family was arrested and sent from the transit camp Westerbork to the Bergen-Belsen concentration camp. Through a prisoner exchange, the family was able to reach Switzerland and later emigrate to the USA. Irene Hasenberg Butter has worked as a peace activist and professor of public health at the University of Michigan and resides in Ann Arbor, Michigan.
