Grace Murray Hooper was an American computer scientist, who was also responsible for developing the first compiler for computer programming language. Eldest among her siblings, Grace was a curious child and went to Hartridge School in New Jersey for preparatory education. She faced rejection from Vassar College for the first time, as she did not have satisfactory marks in Latin. She was accepted the following year, and graduated with her Bachelor’s degree in physics and mathematics. Two years later she earned her Master’s degree in the same discipline from Yale University. While persuing her PhD under Oystein Ore, she taught in Vassar College, where she earned the position of Associate Professor after ten years of service. During World War II, she joined navy and was commissioned as a lieutenant. She was assigned to the Bureau of Ordinance Computation Project in Harvard. After her naval duties ended, she joined Remington Rand, where she worked on UNIVAC. She became the director of automatic programming and sought to find specifications of common business language in computer leading to the discovery of COBOL or Common Business-Oriented Language. This was the first user-friendly computer software and Grace was responsible for advocating the validation process to bring international standardization of computer languages.
