How the telegraph changed the world?
The electric telegraph transformed how wars were fought and won and how journalists and newspapers conducted business. Rather than taking weeks to be delivered by horse-and-carriage mail carts, pieces of news could be exchanged between telegraph stations almost instantly.
How was the telegraph powered?
The Chester battery, shown below, was used in widespread on commercial telegraph lines in the United States. The invention and refinement of the practical battery was critical to the later designs of the telegraph, as they were the first source of constant power.
Does telegraph still exist?
They are well aware of their own anachronism: “Most people are pretty surprised to learn that telegrams still exist, and in fact are still pretty widely used in some parts of the world,” says Colin Stone, Director of Operations.
