VII. Read the information about masters of invention. Be ready to speak about Charles Babbage and Howard Aiken. Charles Babbage (1792-1871).

The Englishman designed the first modern digital computer, but he never built it. He did build other useful devices, though, including a submarine.

Charles Babbage, Master Inventor

English mathematician Charles Babbage designed the first modern computer in the 1830's. He called it an analytical engine.

If Babbage had been able to get enough money to build the computer, the analytical engine would have been as big as a locomotive. It would have been able to store 1,000 50-digit numbers. That was unheard of back then — even though today's machines can store millions of times more information.

Charles Babbage was born the day after Christmas in 1792.'As a child, he liked to take toys apart to see how they were made. He loved to work with math problems. He eventually became a professor at Cambridge University in England.

Babbage could be mean, and he sometimes yelled at people who disagreed with him. But he had a brilliant mind. In addition to designing the forerunner of today's digital computer, Babbage invented a railroad signal system, a device for examining eyes, a submarine and a system of flashing lights for lighthouses.

During the 70 years following Babbage's death in 1871, computer scientists improved on Babbage’s original idea.
