While the director of New York’s City Health Center in Queens, Nyswander studied child health; her resulting study “Solving School Health Problems” is still used by students in public health schools.
During World War II, she set up child care programs for mothers working in defense plants. After the war, she was a professor of public health at the University of California, Berkeley, where she founded the university’s School of Public Health. She apparently knew her stuff: when she died December 18, Nyswander was 104.
