Today I want to tell you a little bit about Charles Babbage. He was an extraordinary Victorian inventor whose ideas helped to lay the foundations for the modern computer more than a century before one was ever built.
He was born in London on the 26th of December 1791. He showed a remarkable ability in mathematics and later studied at Trinity College before transferring to Peterhouse in Cambridge. He got frustrated by the errors that he found in mathematical tables, so he began to search for a way to make calculations more accurate.
In 1822, Babbage designed the Difference Engine, which was a mechanical machine that was intended to calculate and print mathematical tables automatically. The British Government actually funded the project. However, engineering challenges, rising costs and disagreements with his chief engineer meant that it was sadly never completed during his lifetime.
Rather than just abandoning his work, Babbage went on to develop an even more ambitious design which was known as the Analytical Engine. Unlike the Difference Engine, it was intended to follow instructions using punched cards, store information and carry out different calculations. Many of the principles behind it, including a form of memory and a processing unit, are still found in modern computers today.
One of Babbage’s closest collaborators was the mathematician Ada Lovelace. She recognised that the Analytical Engine could do much more than solve mathematical problems and wrote detailed instructions for how it could carry out a complex calculation. Because of this, she is often regarded as the world’s first computer programmer. She really was a remarkable women.
Babbage’s interests extended beyond computing. He also wrote about manufacturing, helped establish the Royal Astronomical Society, campaigned for improvements in science and even designed inventions for the railway, including an early form of the cowcatcher that fitted to the front of locomotives. He also worked on cryptography, postal reform and scientific measurement.
Although neither of his great calculating machines was completed during his lifetime, later engineers proved that his designs were sound. In 1991, London’s Science Museum successfully built a working Difference Engine from Babbage’s original plans using techniques that would have been available in the nineteenth century.
Charles Babbage died in London on the 18th of October 1871, at the age of seventy-nine. Today he is remembered as one of the greatest inventors of the Victorian era. His vision showed that machines could perform complex calculations automatically.
Had he lived to see today’s computers, smartphones and artificial intelligence, what do you think he would have thought?
