Charles Babbage

Charles Babbage was an English mathematician, philosopher, inventor, and Mechanical engineer who is often remembered for his concept of a computer. Charles Babbage credited with being the inventor of the first mechanical computer which eventually led to more complex designs such as the computers we use today. Ada Lovelace was credited with being the first computer programmer. She also translated and wrote literature supporting the project that Babbage invented.

WW2 Colossus

Colossus was the first programmable computer which was designed to break codes in WW2. It was designed by Tommy Flowers and was made of telephone parts. It was originally designed to solve a problem created by mathematician Max Newman. The destruction of many versions of Colossus to delete any evidence or blueprints means that the only working colossus is a replica created in 2007. The colossus computer helped the British to win the war however Hitler did plan to take a closer look at it. But after the decision that is was a waste of money he never did and thankfully it did not lead to having colossus help him to code break and also create more intricate designs.
