When you use apps, play games, or even watch cartoons online—have you ever wondered who made it all possible? Behind every tap and click lies something magical called computer programming, and one brilliant woman named Grace Hopper helped shape it. She wasn’t just a scientist—she was a pioneer who opened the doors to the computer world we live in today.
Early Life: A Curious Kid with a Screwdriver
Grace was born in 1906 in New York City. From the time she was a little girl, she loved taking things apart. Once, she even dismantled all the alarm clocks in her house just to see how they worked! Her mother encouraged her curiosity, and Grace grew up believing that girls could explore science just as much as boys.
She later studied math and physics at college, even though very few women were in those fields at the time.
Working with Computers the Size of Rooms!
During World War II, Grace joined the U.S. Navy. Instead of working on ships, she was assigned to help with one of the world’s first giant computers—the Harvard Mark I.
This machine was as big as a classroom, full of wires, switches, and wheels. Grace loved figuring out how to make it solve problems faster. She quickly became known as someone who could explain computers in simple language.
The Birth of Programming Languages
At that time, computers could only understand complicated math codes. Grace thought: “Why can’t we make computers speak English-like words so everyone can use them?”
This idea was revolutionary! She went on to create COBOL (Common Business-Oriented Language), one of the first programming languages that used words instead of numbers. COBOL made computers easier for people all around the world to use. Even today, some banks and businesses still use it!
Fun Fact: The First “Computer Bug” 🐛
One day, Grace and her team were working on a computer when it suddenly stopped working. After checking, they discovered the problem—a moth had flown inside and got stuck in the machine!
Grace taped the moth into her notebook and wrote “First actual bug found.” That’s how the word “computer bug” became famous.
Do You Know? 🌟
- Grace Hopper was nicknamed the “Queen of Code.”
- She reached the high Navy rank of Rear Admiral, which is a big achievement.
- She loved giving lectures and even showed off pieces of computer wires called “nanoseconds” to explain speed to students.
Grace Hopper’s Legacy
Grace Hopper believed computers should be for everyone, not just scientists. Because of her, we have programming languages that allow apps, games, and even social media to exist today. She opened the world of technology to millions.
When you learn coding at school, you’re walking in Grace Hopper’s footsteps!

Final Thought 💡
Grace Hopper once said:
“The most dangerous phrase in the language is: ‘We’ve always done it this way.’”
She taught us to always think differently, experiment, and dream big.
So next time you code something or play a video game, remember the amazing Grace Hopper—the woman who gave computers a voice!
