Question: What state did Sayre attend college? Passage:Anne Sayre was "born on a train passing through Milwaukee". She spent her childhood in Woodmere, New York, and was educated at Radcliffe College. But the Second World War prevented her to pursue law, her main ambition. To render her service in the war, she worked in the Radiation Laboratory at Massachusetts Institute of Technology. Her job there was managing the supply of special-design transformers. She never really knew what transformers were. She took the job for only a few months, but she met her future husband, David Sayre. (David Sayre was a physics student who also volunteered for war service during his academic break.) They got married in 1947. Married to a scientist, she described herself as "a camp-follower to the scientists". She soon took up writing career, mainly of short stories, of which many were included in the Foley's and the Best American Short Stories collections. In 1949, they moved to England as David Sayre was enrolled for PhD at the University of Oxford to work under Dorothy Hodgkin (a 1964 Nobel laureate). Anne Sayre financially supported most of their financial expenses through her writings. She eventually got appointed as an editor at the Oxford University Press. David received his PhD in 1951, and in September they returned to US. In 1975, Anne revived her ambition to become a lawyer and got enrolled in New York University Law School, from where she graduated with high grades. She devoted her service in legal matters, particularly concerning environment, in Long Island. She initially served as volunteer Legal Aid lawyer in Riverhead. Later, she was appointed justice in the Head of the Harbor, a post she held until illness prompted her to resign in 1996. Since the late 1980s she had suffered from pneumonia and the complications of scleroderma, a rare form of rheumatism. She died on March 13, 1998 in a hospital near her home in Bridgewater Township, New Jersey, and was survived by her husband.
