- Background and education: born in 1906, she studied mathematics and physics at Vassar and obtained a doctorate from Yale; she had a curiosity for engineering since childhood.
- Naval service and Mark I: He enlisted in WAVES, programmed the Mark I at Harvard during World War II and popularized the term 'bug'.
- Technical innovation: He developed the first compiler (A-0) and contributed to the Flow-Matic language, laying the foundations for COBOL and modern programming.
- Legacy and recognitions: She received numerous honorary doctorates and awards, inspired the Grace Hopper Celebration, and had a destroyer, the USS Hopper, named in her honor.
Grace Hopper He was a central figure in the history of computing, known as the «mother of programming». Throughout her life, she not only revolutionized technology, but also challenged gender stereotypes by becoming one of the most influential women In his field.
With an extensive legacy spanning from the creation of the COBOL language until the introduction of the concept of "bug" In computing, its history reflects both its innate intelligence as its unwavering determination to overcome both technical and social barriers.
Grace Hopper's early years
Grace Brewster Murray was born on December 9, 1906 in New York, into a family with a strong military tradition. From an early age, he showed a exceptional curiosity, taking apart clocks in his home to understand how they worked. This interest in the inner workings of things was an early sign of his Passion for science and engineering.
In 1928, he graduated in Maths and physics at Vassar College, a private women's college. She subsequently earned her master's degree in mathematics at Yale University in 1930 and a PhD in 1934 under Øystein Ore. Throughout his studies, he was supported by his family, particularly his father, who believed in the equal opportunities for their children, regardless of their gender.
His entry into the Navy and World War II
During World War II, Grace Hopper enlisted in the Women's Naval Reserve Corps, known as WAVES. In 1944, she graduated as a ship lieutenant at the Naval Reserve Midshipmen's School at Smith College. She was assigned to the Computer Project from the Bureau of Shipping at Harvard University, where he worked with the legendary computer Mark I, one of the first of its kind.
In this role, Hopper collaborated with Howard H. Aiken, performing calculations and programming this revolutionary machine. He quickly stood out for his ability to solve complex problems, which led her to become the third person to program the Mark I.
The concept of "bug" in programming
In 1947, while working on the computer Mark ii, Hopper and his team found a flaw in the system caused by a moth caught in one of the electromechanical relays. The anecdote, although peculiar, marked the first time the term was used "bug" to refer to errors in computer systems. Since then, the word and concept of «debugging» have become an integral part of the programming.
Pioneering contributions: the first compiler
In 1949, Grace Hopper joined the Eckert-Mauchly Computer Corporation, where he worked on the development of the UNIVAC I, the first commercial computer. During his time at this company, he developed the first compiler in 1952, which translated human language into machine code, greatly simplifying the programming process.
This breakthrough, known as the A-0 compiler, laid the foundation for all the modern programming languagesHopper stated that he designed the compiler by "laziness", as he wanted programmers to be able to become mathematicians again instead of spending so much time writing complex codes.
The birth of COBOL
In 1959, Grace Hopper was a key player in the development of COBOL (Common Business-Oriented Language), a programming language designed specifically for business applications. This language, inspired by the Flow-Matic which Hopper had previously developed, made programming easier for people without advanced technical experience and allowed the software portability between different computer systems.
COBOL had a significant impact, not only because it made programming easier, but because it opened the door for the mass use of computers in the business and administrative fields.
Recognitions and legacy
Throughout her life, Grace Hopper received numerous awards and honors, including more than 40 honorary doctorates and National Medal of Technology in 1991. She was also the first American woman to be elected Distinguished Fellow by the British Computer Society in 1973. In 1986, he retired from the Navy with the rank of rear admiral, being the oldest person to retire.
In 1996, the United States Navy christened a destroyer as the USS Hopper in his honor, nicknaming him «Amazing Grace»His influence lives on, not only for his technological contributions, but also for the impact he had on the inclusion of women in the technological field.
Since 1994, the event has been held annually Grace Hopper Celebration of Women in Computing conference, an event dedicated to promoting women's participation in technology and reinforcing the legacy of this extraordinary pioneer.
Grace Hopper's impact on computing is incalculable. Thanks to her innovative spirit and her ability to overcome barriers, she transformed programming into a discipline accessible to all. Her legacy is not only limited to the technical field, but also represents an example of how questioning established boundaries can lead to significant progress in any area of life.
