Who is Grace Hopper? Meet the Queen of Code

Summary

Grace Hopper, known as the 'Queen of Code,' was a trailblazer in the field of computer science. Born in 1906, she graduated with degrees in math and physics and earned a Ph.D. from Yale. Hopper's innovative work on the Harvard Mark I led to the creation of the first compiler, revolutionizing programming languages. As a U.S. Navy Rear Admiral, she championed the use of plain English in programming, making computers more accessible. Her contributions to the UNIVAC I and the development of COBOL laid the foundation for modern computing, and she continued to inspire through teaching until her death in 1992.

Takeaways
