Grace Hopper

Hello! My name is Grace Hopper, and I want to tell you my story. I was born on December 9th, 1906, and even as a little girl, I was very curious. I loved to know how things worked. One time, I wanted to understand how clocks ticked, so I took apart all seven clocks in my house! My mom wasn't too happy about that, but it showed how much I loved figuring things out. That curiosity stayed with me as I grew up, and I fell in love with math and science. It was like solving fun puzzles all the time, and I knew I wanted to spend my life learning and discovering new things.

I grew up and became a math professor at a college, where I enjoyed teaching students all about numbers. But then, a very big event happened in the world called World War II. I knew I had to do something to help my country. So, in 1943, I made a big decision and joined the United States Navy. The Navy leaders saw that I was very good with numbers and had a special job for me. They sent me to work on a top-secret machine. It was one of the very first computers, and it was called the Mark I. It wasn't like the computers you see today—it was huge, as big as an entire room!

Working on the Mark I computer was a great adventure. It was a giant puzzle that I got to help solve every day. I'll tell you a famous story that happened in 1947. One day, the huge machine just stopped working, and we couldn't figure out why. We looked inside all the wires and parts, and guess what we found? A real moth was stuck in one of the switches! We carefully took it out and taped it into our notebook. From that day on, whenever a computer had a problem, we would say we had to 'debug' it. I also had a big idea. I thought computers should be easier for everyone to use. I wanted people to be able to give them instructions in a way that was more like plain English. This idea led to the creation of new computer languages, like COBOL, that helped more people understand and work with computers.

I loved my work so much that I stayed in the Navy for many, many years. I worked hard and eventually became a Rear Admiral, which is a very important leader in the Navy. I always enjoyed encouraging young people to be curious and to learn as much as they could. I lived to be 85 years old. Today, people remember me as a pioneer who helped make computers friendly and useful for everyone, not just for scientists. I hope my story shows you that you should never be afraid to ask 'Why?'.
