William Gilbert

Hello there! My name is William Gilbert, and I lived a very long time ago. I was born in England on May 24th, 1544. When I grew up, I became a doctor, and I was very good at it! In fact, I was so trusted that around the year 1601, I became the personal doctor to the famous Queen Elizabeth I. It was a big job, but my real passion was solving mysteries about the world around me.

I was always fascinated by magnets. How did they pull things without touching them? And why did a compass needle always point north? Instead of just reading old books, I decided to find out for myself by doing lots of experiments. I made a small, round magnet called a 'terrella,' which means 'little Earth.' By moving a tiny compass around it, I discovered something amazing: the little compass behaved just like a big compass does on our planet! That’s when I had a giant idea: the Earth itself is one giant magnet!

Magnets weren't my only puzzle. I also wondered about the strange force you can create by rubbing things, like a piece of amber. When you rub amber, it can pick up tiny feathers and bits of straw. I studied this invisible power and gave it a special Latin name, 'electricus.' That word is where we get our word 'electricity' from today! I wrote all my discoveries down in a big book called 'De Magnete,' which means 'On the Magnet,' and shared it with the world in the year 1600.

I lived to be 59 years old, and I was so happy I could share my ideas. Today, people remember me as the 'father of electricity and magnetism.' My work of doing experiments to test ideas helped other scientists, like the famous Galileo Galilei, learn more about our world. My discoveries were the very first steps in understanding the amazing forces that power so many things we use every day.
