Nancy Roos (February 28, 1905 – April 6, 1957)[1] was a U.S. chess champion.
She was born as Nanny [sic] Krotoschin in Berlin, which was then a part of Prussia, to Georg Krotoschin and Martha Cohn Krotoschin, who were part of a large Jewish family that had lived in Berlin for generations. She married Martin Roos, who had been born in 1903 in Amsterdam, Netherlands.[1] Her place of birth has often been listed incorrectly in various sources as Brussels, Belgium, as that is where she wed Roos in 1936.[2] Before coming to America in 1939, she was active at the Cercle l'Echiquier in Brussels.[2] Roos' sister Eva Krotoschin Beim was murdered in the Holocaust, and her brother Heinz "Henry" Kent survived and later gave videotaped testimony to the USC Shoah Project.
Roos was a professional photographer and at the time of her death was the second highest rated woman in the U.S. Chess Federation.[2]
She died of breast cancer in Los Angeles, California.[2]
