As a result the engines were judged largely on their practical utility to produce error-free tables, and experts of the day did not agree that there was any real need for new tables. In 1833 Babbage met Ada Lovelace, daughter of the notorious British poet Lord Byron, at a party. This, of course, is exactly how computers are used today. In Charles and Ada: the Computer’s Most Passionate Partnership, I look at that personal and professional love affair in detail. Both father and son died bankrupt. While this almost certainly never reached a physical dimension, or at least there is no clear evidence that it did, their relationship was about as close to a love affair as it could possibly have been. Special security devices would ensure the integrity of the results. There was also a widespread perception that a woman should essentially be a decorative ornament, her function being to produce children, run the house and provide the husband with sexual pleasures. She saw that numbers could represent entities other than quantity - letters of the alphabet, notes of music - and that by manipulating numbers, computing machines could extend their powers beyond the world of mathematics. The new design benefited from many of the techniques developed for the more demanding Analytical Engine. Email us at or call 0207 782 4368 . Ada's contributions to computer science were not discovered until the 1950s and have since been recognised in science, literature, theatre and film. His first machine, Difference Engine No.

She was entranced by the small working section of the machine and in time became an enthusiastic supporter of Babbage's work. Most of us don’t use them to make mathematical calculations although, if we need them to do that they can do it for us. Babbage was also a rotten publicist.

Ada was struck by repeated illness throughout her childhood, and in 1829 was subject to a year's bed rest after a bout of measles. Ada, for her part, was a precocious and fascinating child who dreamed of building a flying-machine powered by steam when she was only twelve years old. The Engine was never built.

It is this design that was finally built and completed in 2002, and is the first of Babbage's engine designs to be realized in its entirety.

This was the intention, but one that he failed to realize. In 1980, the U.S. Department of Defence named a newly developed computer language "Ada," after Lovelace. In 1843 Lovelace published an article by the Italian engineer Luigi Menabrea that she translated from French. There they saw the only completed portion of the Difference Engine in action: one-seventh part of it which did work rather well, although of course it did not do everything that the fully working Difference Engine would have done. Some 12,000 unused precision parts were later melted down for scrap. He invented and built the Difference Engine, a mechanical calculator that used the Method of Differences to computer approximate solutions to problems. Ada is known as the first ever computer programmer for designing an early model for a computer more than a century before they were invented.

Difference Engine: The Difference Engine was the first of Babbage's inventions. In a novel I am currently working on, The Ada Lovelace Project, I postulate that this did happen and what the result of it might have been. The grindingly tedious labor of manually checking tables was one thing. It remains amongst the most celebrated icons in the prehistory of automatic computation. Ada was given a good education at home by tutors and governesses hired by her mother, Lady Byron. It was believed at the time - at least by men - that women were less intelligent than men because they had on average smaller brains. There is also a fair amount of surviving correspondence between them – though there are far more letters from Ada to Babbage than vice versa – and also considerable contemporary comments about them because they were famous even in their own time. Lovelace speculated that the machine might go beyond numbers and more generally manipulate symbols in accordance with rules. This remarkable and indeed wonderful endeavour proved that Babbage’s Difference Engine could have been built in the nineteenth century. He was apparently set for a life of quiet, relatively obscure mathematical prowess until, one summer day in 1821 – the exact day is not known – Babbage had a prodigiously important epiphany. But Babbage, in a disastrous act that resonates down the nineteenth century, rejected Ada’s suggestion and consequently there never was a computer revolution in 1843.

Since 2009 her life has been celebrated through an annual event on the second Tuesday of October to raise the profile of women in science, technology, engineering and maths (STEM) and to create new role models for girls and women in the field. 1 called for 25,000 parts and would have weighed an estimated four tons.
