The daughter of a romantic poet and occasional freedom fighter, Ada Lovelace had a famous but absent father. She never knew Lord Byron, as just weeks after her birth in 1815, he divorced her mother Isabella Milbanke Byron and left to fight in the Greek War of Independence. In an effort to prevent Ada from developing her father's unpredictable temper, Isabella decided that her daughter should devote her life to study.
Ada studied hard despite the fact that society did not encourage women pursuing interests in science. Her life changed when she met inventor Charles Babbage at a party. As he demonstrated a working section of his mechanical calculator, Ada was taken in by how it worked and wanted to know more. Impressed by the 17-year-old's obvious passion, Babbage became her tutor. Ada married in 1835 and became a mother, but she continued to take an active interest in study, socialising in intellectual circles with the likes of Charles Dickens and Michael Faraday.
Ada stayed in contact with Babbage, who in 1837 had proposed a new machine, the analytical engine. In 1843, Ada was asked to translate a French text written by engineer Luigi Menabrea about Babbage's new design. After completing the translation, Ada was encouraged by Babbage to write her own notes on his work.
After nine months of hard work, Ada presented Babbage with a detailed list of notes that was three times longer than the original article. In her calculations, Ada wrote what are considered the first ever computer algorithms to be used in a new type of machine. She essentially provided the first ideas for computer programming in what was a groundbreaking proposal on the potential of computers.
Ada died of cancer aged only 36 and her work was largely recognised until the 1950s when her notes were republished. In 1979 the US Department of Defence named a programming language ‘Ada' in her honour.
