Who Invented the First Electric Battery?
When we talk about electric batteries, we often talk about voltage. But did you know that this word is named after the person who invented the first electric battery? First, let’s take a look at what a volt is, and then we’ll find out more about the guy who gave the ‘volt’ its name.
What is a Volt?
A volt is defined as a unit of electric potential and electromotive force, and voltage refers to the number of those units. That sounds a lot more complicated than it is! If you think of the water in a tap being like the electricity running through a wire, the voltage means the amount of pressure. This video is quite long but explains it very well.
Why are Volts Called Volts?
Alessandro Volta
The term actually comes from a name. It was coined in honour of Italian physicist Alessandro Volta, who is recognised as the inventor of the first electric battery. During the 1790s, Volta worked on the theories of electricity of the day.
Volta disagreed with the theory proposed by fellow Italian scientist Galvani that electricity was generated by animal tissue. Instead of experimenting on frogs or other animals, Volta did experiment after experiment with metals.
His persistence paid off, and in 1800, he invented the world’s first battery, known as the ‘voltaic pile’.
The Voltaic Pile
This voltaic pile was simple but ingenious. It consisted of a pile of zinc and silver discs. But alternating between them was a piece of cardboard, or a piece of cloth, that had been soaked in saltwater.
There was a wire that connected the zinc disc on the bottom to the silver disc on the top, and this wire was capable of producing sparks.
What else Did Volta Invent?
The invention of the first electric battery brought Volta the most fame and recognition, but he also made other discoveries. He invented the electrophorus, a device that could transfer an electrical charge to other objects, as well as an electrical condensor, and the voltaic cell.
He is also known for having discovered and isolated methane gas. After his death, the volt and voltage were named in his memory.
What about Galvani?
Luigi Galvani
Yet there is one more twist to the tale. Volta’s longstanding colleague Galvani of the animal electricity theory also left his name in our language. When we say ‘galvanise’ or ‘galvanism’, that is where it comes from.
Despite their differing theories, there was no rivalry between the two scientists. They were both more concerned with the pursuit of knowledge than with whose theory would prove to be right, and it was Volta who first coined the word ‘galvanismo’ in Italian.

Living in History
Now you know what reenactment is, from Alison’s excellent article, you may want to know a bit more about how it all works. How much work is involved in sewing the clothes, what do they eat, how do they get around? Alison’s mother Jax has written a great article about all this and more
It wasn’t an easy life, living in Tudor times. You can find that out by reading about it in a variety of places.
But I found it out by living it at Kentwell Hall.
We do reenactment. We being our entire family, from my son who was a Tudor baby aged 4 months last summer, through to my partner Tim.
Tips for Moving to a New School
Moving to a new school is always scary, whether you’re moving from primary school to high school or into a new school in a different area. What can you do to make it easier?
My kids are old hands at this because they’ve moved school so often, even going into schools in a new country where they haven’t known the language. We’ve lived in Germany, Switzerland and UK and they’ve been to local schools speaking German, French and English. It wasn’t ever easy but they’ve made great friends who they still keep in touch with now that they’ve moved on.
I asked them for their advice on moving to a new school.
Being a Teenage Vegetarian
What do you do when you want to become a vegetarian but your parents aren’t too keen? Tabitha explains how her family reacted to her decision, how they have adapted to having a teenage vegetarian in the family and how she eats healthily without meat.
Like a lot of teenagers, I decided to become a vegetarian. Some do so because they want to rebel, some people think it will be healthier, or just don’t like meat that much. I was convinced to go veggie when I was 13 after a biology dissection. It was only a rat, but it made me realise that I didn’t want to be eating animals as I have a pet rabbit and it was just too close to home for me. Also, a Jamie Oliver programme I accidentally watched featuring the making of sausages put me right off… But mainly for me, it was the animals.
