The first ever computer manual which was written by a Victorian woman 175 years ago has been sold at auction for nearly £100,000 -  nearly 20 times its expected price.

The edition, 'Sketch of the Analytical Engine by by L.F. Menabrea with notes by Ada Lovelace', was snapped up by an anonymous buyer after being sold by Moore Allen & Innocent in Cirencester, Glocestershire. 

Ada, the only legitimate child of poet Lord Byron, was a maths prodigy who died aged 36. 

A rare book by Ada Lovelace, the Victorian woman renowned as the world's first computer programmer has sold at auction for £95,000

During her short life, she played a key role in the early development of computer programming, becoming friends with mathematician Charles Babbage over his automatic mechanical calculator, the Difference Engine. 

Lovelace played a key role in the 1843 book 'Sketch of the Analytical Engine', of which just seven copies are thought to exist - one of which sold at auction for £95,000.

Before going under the hammer on Friday (20/7), the book was described by auctioneer Philip Allwood as 'the first separate edition of arguably the most important paper in the history of digital computing before modern times'.  

It was signed by 'Lady Lovelace' and was originally expected to sell for between £3,000 to £5,000.

During her short life Lovelace became friends with mathematician Charles Babbage, over his automatic mechanical calculator, the Difference Engine

Lovelace was the first person to recognise that Babbage's machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine.

As a result, she is regarded as the first person to recognise the full potential of a 'computing machine' and the first 'computer programmer'.

After eight years of work, Charles Babbage unveiled his plans for the Analytical Engine at a seminar at the University of Turin in 1840.

Attending the seminar was Italian military engineer and mathematician L.F. Menabrea, who went on to serve as the country's Prime Minister.

Menabrea reported the presentation the following year in an obscure Swiss publication, and Babbage urged Lady Lovelace to translate the report into English.

The 175-year-old book by the world's first computer programmer  was found in a 'box of junk'

The book was snapped up by an anonymous buyer after being sold by Moore Allen & Innocent in Cirencester, Glos

The book was signed by 'Lady Lovelace' and was originally expected to sell for between £3,000 to £5,000

A Cotswolds book dealer acting on behalf of an anonymous buyer successfully bid for 'Sketch of the Analytical Engine

The book was described as 'the first separate edition of arguably the most important paper in the history of digital computing before modern times'

Only six copies of the 'geeky' book are known to exist, with two of them owned by Harvard University in the US

Lovelace was finally credited as the translator for the book, four years after she died

She did, and also added her own explanatory notes, which were substantially longer than Menabrea's original article and included what many consider to be the first computer program - an algorithm designed to be carried out by the machine.

The resulting work was published in 1843 as 'Sketch of the Analytical Engine invented by Charles Babbage Esq by L.F. Menabrea of Turin, officer of the Military Engineers, with notes by the translator'.

Lovelace's identity as the translator remained a mystery and it wasn't until 1848, four years after her death aged just 36, that she was finally credited. 

Who was Ada Lovelace?

• 'Ada Lovelace' was born Ada Gordon in 1815, and is the sold child of the marriage of the erratic poet George Gordon, Lord Byron, and his mathematics-loving wife Annabella Milbanke

• She was raised under her mother's strict regime of science, logic and maths
• During her childhood Ada had a fascination with machines and designed fanciful boats and steam flying machines

• Aged 19, she married, William King. When her husband was made Earl of Lovelace in 1838 his wife became Lady Ada King
• In 1833, she met Charles Babbage, and was intrigued by Babbage's plans for a tremendously complicated device he called the Analytical Engine

• Ada Lovelace died of cancer at 36, a few short years after the publication of 'Sketch of the Analytical Engine, with Notes from the Translator'

Who was Charles Babbage? 

• Babbage was a British mathematician, an original and innovative thinker and a pioneer of computing.

• He was born on 26 December 1791, probably in London, the son of a banker. 

• By the time he went to Cambridge University in 1810 he was very interested in mathematics
• After graduation Babbage was hired by the Royal Institution to lecture on calculus and was Lucasian Professor of Mathematics at Cambridge.

• The 1820s saw Babbage work on his 'Difference Engine', a machine which could perform mathematical calculations.
• He also worked on another invention, the more complex Analytical Engine, a revolutionary device on which his fame as a computer pioneer now largely rests. 
• It was intended to be able to perform any arithmetical calculation using punched cards that would deliver the instructions, as well as a memory unit to store numbers and many other fundamental components of today's computers.

Charles Babbage died at his home in London on 18 October, 1871
