The first mechanical computer was the Difference Engine built in 1822 by Charles Babbage, considered as the "father of the computer." Between 1847 and 1849, he made an improved version of his first model, which he called Difference Engine No. 2. However, the machine was not transformed into a full-scale functional device due to lack of funding.Know More
The Difference Engine did not resemble the modern computers of today. It was massive and consisted of up to 25,000 components. The machine weighed 15 tons and was 8 feet tall.
In 1991, the London Science Museum completed the Difference Engine No. 2 to commemorate the bicentennial of Babbage's birth year.Learn more about Computer History

In 1822, Charles Babbage first idealized a machine capable of making computations. In 1936, Alan Turing created the first modern-style computer, and Konrad Zuse created the first electronic-programmable computer. In 1942, John Vincent Atanasoff created the first digital computer. In 1953, IBM designed and marketed the first mass-produced computer.Full Answer >
According to a 1986 contest held by Boston's Computer Museum, the first true computer was the Kenbak-1, designed by John Blankenbaker in 1971. The Kenbak-1 is considered the first personal computer, although it had no microprocessor and used small- and medium-scale integrated circuits.Full Answer >
