Biography of Famous Mathematicians Grace Hopper
Grace Hopper: Pioneer in Computer Science and Programming
Early Life and Education:
Grace Brewster Murray Hopper was born on December 9, 1906, in New York City, USA. She was the eldest of three children born to Walter Murray, a successful insurance broker, and Mary Campbell Van Horne. Hopper’s childhood was marked by an early fascination with machines and gadgets, showing signs of her future interest in technology.
In 1928, Hopper graduated Phi Beta Kappa from Vassar College with a bachelor’s degree in mathematics and physics. She then went on to earn a master’s degree in mathematics from Yale University in 1930. While at Yale, Hopper had the opportunity to work with the renowned mathematician Oystein Ore.
Early Career and Marriage:
After completing her master’s degree, Hopper taught mathematics at Vassar College for a brief period. In 1934, she married Vincent Foster Hopper, an NYU professor, but the marriage ended in divorce in 1945.
With the outbreak of World War II, Hopper was eager to contribute her mathematical skills to the war effort. In 1943, she joined the United States Navy Reserve (WAVES), where her mathematical expertise led her to work on the Harvard Mark I, one of the earliest electromechanical computers.
Harvard Mark I and the Birth of Computer Programming:
Working on the Harvard Mark I, Hopper became one of the first programmers in history. She learned to program the massive machine using punched cards, developing a keen understanding of its operations. During this time, she coined the term “bug” to describe a computer glitch when an actual moth caused a malfunction in the Mark II computer.
Hopper’s work on the Harvard Mark I laid the groundwork for her future contributions to computer programming and software development.
UNIVAC and COBOL:
After World War II, Hopper remained in the Navy and joined the team working on the UNIVAC I (Universal Automatic Computer), one of the earliest commercially produced computers. Here, she continued to advance her programming skills and gained a reputation as a pioneering computer scientist.
In the 1950s, Hopper developed the first compiler, a program that translates written instructions into machine code. Her compiler, named A-0, was a precursor to the COBOL (Common Business-Oriented Language) programming language, which she later co-developed. COBOL became one of the most widely used programming languages for business applications.
Later Career and Retirement:
Grace Hopper retired from the Navy as a Rear Admiral in 1986, but her influence in the world of computing continued. She received numerous awards and honors for her contributions, including the Presidential Medal of Freedom in 2016, posthumously.
Hopper passed away on January 1, 1992, but her legacy lives on. Her pioneering work in computer programming, compiler development, and the promotion of standardized programming languages left an indelible mark on the field of computer science. Today, she is celebrated as a trailblazer and a role model for women in technology.
