Why Is Grace Murray Hopper Important to World History?

Grace Murray Hopper was an American computer scientist and mathematician who made significant contributions to the field of computer science. She was born on December 9, 1906, in New York City and passed away on January 1, 1992. Her work revolutionized the way we use computers today, and she is considered one of the most important figures in world history.

Early Life and Education

Grace Hopper grew up in a family that valued education. Her parents encouraged her to pursue her interests in mathematics and science, which were rare for women at the time. She earned a degree in mathematics from Vassar College in 1928 and went on to earn a master’s degree in mathematics from Yale University in 1930.

Military Career

During World War II, Grace Hopper joined the United States Navy Reserve as a lieutenant. She worked on the Mark I computer project at Harvard University, where she helped develop one of the first compilers, which translates high-level programming languages into machine code.

In the late 1940s, Hopper worked on the UNIVAC I computer project at the Eckert-Mauchly Computer Corporation. She developed a new programming language called FLOW-MATIC that allowed users to write programs using English-like commands instead of numerical codes. This innovation made it easier for people without a technical background to use computers.


Grace Hopper’s contributions to computer science were groundbreaking. She is credited with inventing the first compiler and developing COBOL (Common Business-Oriented Language), one of the first high-level programming languages still used today.

Hopper was also an advocate for diversity and inclusion in technology fields. She encouraged women to pursue careers in computer science, even when it was not socially accepted.

Today, Grace Hopper is celebrated with numerous awards and honors. The Grace Hopper Celebration of Women in Computing is an annual conference that brings together women in technology to network and learn from one another.


Grace Murray Hopper’s life and work have had a significant impact on the world we live in today. Her contributions to computer science have transformed the way we use computers, and her advocacy for diversity and inclusion has paved the way for future generations of women in technology.

We owe a great debt of gratitude to this remarkable woman, who broke barriers and changed the course of history.
