Claude Shannon

Hello! My name is Claude Shannon. I was born on April 30th, 1916, in a small town in Michigan. Ever since I was a boy, I loved tinkering and building things. My hero was the great inventor Thomas Edison, and I wanted to be just like him. I was always busy with projects, like building model airplanes that could really fly and a boat that I could control with a radio. One of my favorite creations was a telegraph system I made from old fence wire. It stretched a half-mile to my friend's house, and we could send messages back and forth in code!

My love for math and science led me to college to become an engineer. In 1937, while I was a student at a famous school called the Massachusetts Institute of Technology, or MIT, I wrote a very important paper for my master's degree. It might sound complicated, but the idea behind it was quite simple and very powerful. I realized that electrical circuits, which can be either ON or OFF, could be used to solve logic problems. You can think of it like a light switch in your room. When the switch is ON, it could mean 'true,' and when it's OFF, it could mean 'false.' I figured out that by connecting many of these switches together, you could build a machine that could 'think' and solve even the most complex math problems. This single idea became the basic building block for every digital computer that exists today.

During World War II, I went to work at a famous research center called Bell Labs. The work I did there was top secret! My job was in a field called cryptography, which is the science of making and breaking secret codes. It was incredibly important work because it helped keep important messages safe from enemies during the war. As I worked with these secret messages, I started thinking about an even bigger idea. I wondered, what is information, really? How can we measure it? And how can we send it perfectly from one place to another without any mistakes or errors?

In 1948, I published a paper that finally answered those big questions. In it, I showed that all information—whether it’s words in a book, sounds in a song, or even pictures—could be broken down into tiny, simple pieces. I gave the smallest possible piece of information a special name: a 'bit.' A bit is just a simple choice, like yes or no, or on or off. My idea, which became known as Information Theory, changed everything. It created the blueprint for our entire digital world. It's the reason we have computers, the internet, smartphones, and digital music. Every time you use technology, you are using my theory.

Even though my work was very serious, I never stopped having fun and being playful. I loved to juggle, and I could even ride a unicycle—sometimes I would do both at the same time! I also continued to build amazing gadgets just for fun. I once built a mechanical mouse I named Theseus that was smart enough to solve a maze all by itself. I even built a trumpet that could shoot flames! I always believed that being playful and curious was the best way to be creative and discover new things.

I lived to be 84 years old, and I was very lucky to see how many of my ideas changed the world. Today, people often call me 'the father of the information age.' Every time you send a text message, watch a video online, or use a computer, you are using the ideas about 'bits' and information that I discovered so many years ago. My work is like the invisible magic that connects our modern world.
