Summary
[edit]DescriptionGravesite for U.S. Navy Admiral Grace Hopper.jpg |
English: Gravesite for U.S. Navy Adm. Grace Hopper in Section 59 of Arlington National Cemetery, Arlington, Virginia, June 27, 2017. Hopper was a mathematician and a pioneer in computer science. At a time when few women pursued science or engineering degrees, Hopper earned her Ph.D. in mathematics from Yale University in 1934. She was a professor of mathematics at Vassar College (her undergraduate alma mater) until 1943, when she joined the U.S. Naval Reserve as a lieutenant. Assigned to the Bureau of Ships Computation Project at Harvard University, Hopper worked on Mark I, the first large-scale automatic calculator (a precursor of the computer). After the war, she remained at the Harvard Computation Lab for four years as a research fellow. In 1949, she joined the Eckert-Mauchly Computer Corporation, where she helped to develop the UNIVAC I, the first general-purpose electronic computer. Throughout her postwar career in academia and private industry, Hopper retained her naval commission. From 1967 to 1977, she directed the Navy Programming Languages Group in the Navy's Office of Information System Planning. When Rear Adm. Hopper retired from the Navy in 1986 at the age of 79, she was the oldest officer on active U.S. naval duty. (U.S. Army photo by Elizabeth Fraser / Arlington National Cemetery / released) |
