Grace Hopper

Born on 9th December 1906, She was a pioneering computer scientist and Rear Admiral in the U.S. Navy and played a crucial role in shaping early programming practices.

She worked on the Harvard Mark I computer, one of the first large-scale automatic calculators.

Moreover, Hopper believed programming should be more accessible; therefore, she helped develop the first compiler, which translated human-readable instructions into machine code.

She was also instrumental in creating COBOL (Common Business-Oriented Language), making computers usable for business and administrative purposes.

Additionally, she popularized the term “debugging” after removing an actual moth from a computer system.

Her legacy continues in modern programming, where user-friendly languages remain central to technological development.
