Grace Murray Hopper, born December 9, 1906, was a mathematics professor who enlisted in the United States Navy at the start of World War II. During his involvement, Hopper developed several new programming languages, including COBOL, which is still one of the most widely used programming languages ​​today. Hopper was also one of the first to coin the term "computer bug". During her life, Grace Hopper influenced many people through her military service and led a movement in modern electronics through her work. Born in 1906 in New York, Grace Hopper grew up a curious child. From a young age, she tinkered with small electronic devices, including taking apart clocks and other machines. His mother taught him geometry, a practice frowned upon at the time. Murray went to college and earned a bachelor's degree in mathematics and physics. Just two years later, in 1930, she earned a master's degree in mathematics from Yale and became a professor of mathematics at Vassar. During her tenure as an instructor, she earned a Ph.D. from Yale and was later promoted to instructor. In 1936, she published an article in a mathematical journal, American Mathematical Monthly, entitled "The Ungenerated Seven as an Index to Pythagorean Number Theory." When World War II broke out, Grace Hopper made the difficult decision to enlist in the war effort as a naval enlisted man. However, she was both underweight and too old to enlist, and she was serving in a "critical position" as determined by the Navy. The Navy asked Hopper to remain a citizen, but Hopper returned with a medical exemption. special government permission and a leave of absence from Vassar College (Riddle, Agnes Scott College).
