Facts About The First Computer

Charles Babbage invented the first computer, called the Difference Engine. How on earth did it work?

The Difference Engine is the first automatic, mechanical calculator designed by British mathematician Charles Babbage, who proposed its construction in 1822 to the Royal Astronomical Society.

He suggested the machine would employ the decimal number system and would be powered by turning a handle, as a method to calculate mathematical tables mechanically, therefore removing the high rate of human error.

At first Babbage received financial backing from the British Government, but this was later pulled when no apparent progress had been made on constructing the device. The inventor went on to design a more general analytical engine and then later in 1847 an improved engine design – the Difference Engine No. 2.

Did you know … The first Difference Engine was made up of 25,000 parts, weighing 13.6 tons and was 2.4m high.

Faithful to the original designs the machine consists of over 8,000 parts, weighs five tons and measures 11 feet in length.

In 2000 the printer which he plotted to accompany the engine was added and together performed as the inventor had intended over a century before. The completion of the machine ended a long-standing debate as to whether Babbage’s designs would’ve worked.

Did you know … The London Museum of Science constructed a fully functional Difference Engine 2 between 1989 and 1991 in honor of the 200th anniversary of Babbage’s birth

Charles Babbage

Born in London in 1791, Charles Babbage was a mathematician, philosopher, inventor and mechanical engineer. He was formerly tutored as a child in Devon and Middlesex, and in 1810 he attended Trinity College where he claimed to be disappointed in the mathematical education available.

Did you know … The first of these devices was imagined in 1786 by J.H. Müller…

In 1814 he married Georgiana Whitmore and moved to Dudmaston Hall in Shropshire where Babbage engineered the central heating system. The couple had eight children, three of which survived to adulthood.

In 1827 Charles’ wife, father and at least one son died, it was these sad events which caused the inventor to suffer a mental breakdown, delaying the construction of many of his machines.

Did you know … He was attending high school King Edward VI for a short time, but due problems with his medical condition he had to study privately.

He died aged 79, it is thought of ‘renal inadequacy, secondary to cystitis’. Half of his brain is preserved in the Hunterian Museum in the Royal College of Surgeons, London.
