Edmond Becquerel

Hello! My name is Edmond Becquerel. I was born in the beautiful city of Paris, France, way back on March 24th, 1820. My house was a very exciting place because my father, Antoine, was a famous scientist! Instead of toys, our home was filled with wires, glass tubes, and bubbling potions. I loved watching him work in his laboratory, and I knew from a very young age that I wanted to be a scientist, just like him.

When I grew up, I became my father’s assistant. One day in 1839, when I was only 19 years old, I was doing an experiment. I put two metal plates made of platinum into a special liquid. When I let sunlight shine on one of the plates, something amazing happened—I saw a little bit of electricity being created! I realized that light itself could make power. I called this the 'photovoltaic effect.' 'Photo' means light, and 'voltaic' means electricity. I had discovered how to make light-electricity!

Discovering the photovoltaic effect was just the beginning. I became fascinated with light and all its secrets. I studied things that glow in the dark, a phenomenon called phosphorescence. I also worked on taking some of the very first color photographs, trying to capture all the beautiful colors of a rainbow made by sunlight. Light was like a magical puzzle, and I spent my whole life trying to figure it out.

I lived to be 71 years old, and I was so happy I got to spend my life as a scientist. My discovery of the photovoltaic effect was a very important first step. Today, other clever scientists have used my idea to build something amazing: solar panels! When you see a shiny panel on a roof, soaking up the sun's rays to make power for a house, you are seeing my discovery at work. My little experiment from long ago is now helping to power our world in a clean, bright way.
