Alessandro Volta

Hello! My name is Alessandro Volta. I was born a very long time ago, on February 18th, 1745, in a beautiful town in Italy called Como. Even when I was a little boy, I was full of curiosity. I loved watching thunderstorms and was fascinated by the crackle and spark of electricity! My family wanted me to become a lawyer, but my heart was always buzzing with questions about science and how the world worked.

When I grew up, I became a professor in 1774 so I could spend my days doing experiments. Around 1776, I even discovered a new kind of gas that we now call methane! One day, I heard about another scientist named Luigi Galvani. He had seen that frog legs would twitch if they were touched by two different kinds of metal. He believed the electricity came from the animal itself. I thought about this for a long time and had a different idea. I asked myself, 'What if the electricity is coming from the metals instead?'.

I started testing my idea right away. I gathered up round discs of copper and zinc and stacked them one on top of the other, like a pile of coins. Between each pair of metal discs, I slipped a piece of cardboard that I had soaked in salt water. Then, I connected a wire to the top and bottom of my pile. When I touched the wires, I felt a little tingle! I had created a steady flow of electricity. Around the year 1800, I shared my invention with the world. I called it the 'voltaic pile,' and it was the very first battery! My work was so exciting that in 1801, even the famous leader Napoleon Bonaparte wanted to see it, and he thought it was magnificent.

I lived a long and exciting life filled with discovery. I lived to be 82 years old. My work helped people understand and use electricity in amazing new ways that changed the world. Today, the power of electricity is measured in 'volts,' a unit named right after me! Every time you use a battery to power a toy or a flashlight, you are using an idea that started with my curious mind and a simple pile of metal discs.
