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.

Unsung Heroes – Lollipop Men and Women
Is there a Lollipop Man or Woman on your road to school? Do you know his or her name?
When I take my children to school, we walk if we can, because the parking situation near the school is a bit difficult. On our way we cross the road where the Lollipop Man stands guard.
He isn’t particularly talkative, but is friendly and helpful. It has been warm these past days, and still he stands, in his reflective jacket and ear-muffed reflective hat. I am waiting for him to take the hat off, he must be sweltering under there. Perhaps he has a lighter hat in his cupboard, which doesn’t get worn until summer.

A Poem – Sadness is a Storm
This poem was sent to us by one of our talented young readers, 14 year old Rebekah.
Sadness is a storm.
A clap of thunder,
As you howl and wail,
Yet through it all,
You still prevail.
Nothing withstands
The heart of the tempest.
Ominous clouds loom,
Lightning flashes.
Light still gets through.
It gives you a glimpse,
Of hope pure and true
All’s well once more,
With the subsiding of the storm.
