Ada Lovelace

1799

The Manor had been built as a hunting lodge in 1799 and was improved by King in preparation for their honeymoon.

1815

Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine.

1816

On 16 January 1816, at Lord Byron's command, Lady Byron left for her parents' home at Kirkby Mallory, taking their five-week-old daughter with her.

Babbage certainly helped and commented on Ada's work, but she was definitely the driver of it." Wolfram then suggests that Lovelace's main achievement was to distill from Babbage's correspondence "a clear exposition of the abstract operation of the machine—something which Babbage never did." ==In popular culture== ===1810s=== Lord Byron wrote the poem "Fare Thee Well" to his wife Lady Byron in 1816, following their separation after the birth of Ada Lovelace.

1822

Allegra died in 1822 at the age of five.

1824

He died in 1824 when she was eight years old.

1829

In June 1829, she was paralyzed after a bout of measles.

1831

By 1831, she was able to walk with crutches.

1832

During her final illness, she would panic at the idea of the younger Crosse being kept from visiting her. ===Education=== From 1832, when she was seventeen, her mathematical abilities began to emerge, and her interest in mathematics dominated the majority of her adult life.

1833

Lovelace first met him in June 1833, through their mutual friend, and her private tutor, Mary Somerville. Between 1842 and 1843, Ada translated an article by Italian military engineer Luigi Menabrea on the calculating engine, supplementing it with an elaborate set of notes, simply called "Notes".

Despite the illnesses, she developed her mathematical and technological skills. Ada Byron had an affair with a tutor in early 1833.

Lovelace did have some contact with Elizabeth Medora Leigh, the daughter of Byron's half-sister Augusta Leigh, who purposely avoided Lovelace as much as possible when introduced at court. ===Adult years=== Lovelace became close friends with her tutor Mary Somerville, who introduced her to Charles Babbage in 1833.

In 1851, the year before her cancer struck, she wrote to her mother mentioning "certain productions" she was working on regarding the relation of maths and music. Lovelace first met Charles Babbage in June 1833, through their mutual friend Mary Somerville.

1834

She was presented at Court at the age of seventeen "and became a popular belle of the season" in part because of her "brilliant mind." By 1834 Ada was a regular at Court and started attending various events.

This description followed their meeting on 24 February 1834 in which Ada made it clear to Hobhouse that she did not like him, probably due to her mother's influence, which led her to dislike all of her father's friends.

1835

She married William King in 1835.

This first impression was not to last, and they later became friends. On 8 July 1835, she married William, 8th Baron King, becoming Lady King.

1836

Other historians reject this perspective and point out that Babbage's personal notes from the years 1836/1837 contain the first programs for the engine.

From 1845, the family's main house was Horsley Towers, built in the Tudorbethan fashion by the architect of the Houses of Parliament, Charles Barry, and later greatly enlarged to Lovelace's own designs. They had three children: Byron (born 12 May 1836); Anne Isabella (called Annabella, born 22 September 1837); and Ralph Gordon (born 2 July 1839).

1837

From 1845, the family's main house was Horsley Towers, built in the Tudorbethan fashion by the architect of the Houses of Parliament, Charles Barry, and later greatly enlarged to Lovelace's own designs. They had three children: Byron (born 12 May 1836); Anne Isabella (called Annabella, born 22 September 1837); and Ralph Gordon (born 2 July 1839).

Bromley notes several dozen sample programs prepared by Babbage between 1837 and 1840, all substantially predating Lovelace's notes.

1838

King was made Earl of Lovelace in 1838, Ada thereby becoming Countess of Lovelace. Her educational and social exploits brought her into contact with scientists such as Andrew Crosse, Charles Babbage, Sir David Brewster, Charles Wheatstone, Michael Faraday and the author Charles Dickens, contacts which she used to further her education.

Immediately after the birth of Annabella, Lady King experienced "a tedious and suffering illness, which took months to cure." Ada was a descendant of the extinct Barons Lovelace and in 1838, her husband was made Earl of Lovelace and Viscount Ockham, meaning Ada became the Countess of Lovelace.

1839

From 1845, the family's main house was Horsley Towers, built in the Tudorbethan fashion by the architect of the Houses of Parliament, Charles Barry, and later greatly enlarged to Lovelace's own designs. They had three children: Byron (born 12 May 1836); Anne Isabella (called Annabella, born 22 September 1837); and Ralph Gordon (born 2 July 1839).

1840

She apparently lost more than £3,000 on the horses during the later 1840s.

In the 1840s, the mathematician Augustus De Morgan extended her "much help in her mathematical studies" including study of advanced calculus topics including the "numbers of Bernoulli" (that formed her celebrated algorithm for Babbage's Analytical Engine).

Part of the terrace at Worthy Manor was known as Philosopher's Walk, as it was there that Lovelace and Babbage were reputed to have walked while discussing mathematical principles. ===First computer program=== In 1840, Babbage was invited to give a seminar at the University of Turin about his Analytical Engine.

Bromley notes several dozen sample programs prepared by Babbage between 1837 and 1840, all substantially predating Lovelace's notes.

1841

When it became clear that Carpenter was trying to start an affair, Ada cut it off. In 1841, Lovelace and Medora Leigh (the daughter of Lord Byron's half-sister Augusta Leigh) were told by Ada's mother that Ada's father was also Medora's father.

On 27 February 1841, Ada wrote to her mother: "I am not in the least astonished.

1842

Lovelace first met him in June 1833, through their mutual friend, and her private tutor, Mary Somerville. Between 1842 and 1843, Ada translated an article by Italian military engineer Luigi Menabrea on the calculating engine, supplementing it with an elaborate set of notes, simply called "Notes".

He called her "The Enchantress of Number." In 1843, he wrote to her: During a nine-month period in 1842–43, Lovelace translated the Italian mathematician Luigi Menabrea's article on Babbage's newest proposed machine, the Analytical Engine.

Luigi Menabrea, a young Italian engineer and the future Prime Minister of Italy, transcribed Babbage's lecture into French, and this transcript was subsequently published in the Bibliothèque universelle de Genève in October 1842. Babbage's friend Charles Wheatstone commissioned Ada Lovelace to translate Menabrea's paper into English.

1843

Lovelace first met him in June 1833, through their mutual friend, and her private tutor, Mary Somerville. Between 1842 and 1843, Ada translated an article by Italian military engineer Luigi Menabrea on the calculating engine, supplementing it with an elaborate set of notes, simply called "Notes".

In 1843–44, Ada's mother assigned William Benjamin Carpenter to teach Ada's children and to act as a "moral" instructor for Ada.

He called her "The Enchantress of Number." In 1843, he wrote to her: During a nine-month period in 1842–43, Lovelace translated the Italian mathematician Luigi Menabrea's article on Babbage's newest proposed machine, the Analytical Engine.

These notes, which are more extensive than Menabrea's paper, were then published in the September 1843 edition of Taylor's Scientific Memoirs under the initialism AAL. Ada Lovelace's notes were labelled alphabetically from A to G.

. == Publication history == Six copies of the 1843 first edition of Sketch of the Analytical Engine with Ada Lovelace's "Notes" have been located.

1844

She had a shadowy relationship with Andrew Crosse's son John from 1844 onwards.

In 1844 she commented to a friend Woronzow Greig about her desire to create a mathematical model for how the brain gives rise to thoughts and nerves to feelings ("a calculus of the nervous system").

As part of her research into this project, she visited the electrical engineer Andrew Crosse in 1844 to learn how to carry out electrical experiments.

1845

From 1845, the family's main house was Horsley Towers, built in the Tudorbethan fashion by the architect of the Houses of Parliament, Charles Barry, and later greatly enlarged to Lovelace's own designs. They had three children: Byron (born 12 May 1836); Anne Isabella (called Annabella, born 22 September 1837); and Ralph Gordon (born 2 July 1839).

1851

The gambling led to her forming a syndicate with male friends, and an ambitious attempt in 1851 to create a mathematical model for successful large bets.

In 1851, the year before her cancer struck, she wrote to her mother mentioning "certain productions" she was working on regarding the relation of maths and music. Lovelace first met Charles Babbage in June 1833, through their mutual friend Mary Somerville.

On 12 August 1851, when she was dying of cancer, Lovelace wrote to him asking him to be her executor, though this letter did not give him the necessary legal authority.

1852

Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine.

Her mindset of "poetical science" led her to ask questions about the Analytical Engine (as shown in her notes) examining how individuals and society relate to technology as a collaborative tool. She died of uterine cancer in 1852 at the age of 36. ==Biography== ===Childhood=== Lord Byron expected his child to be a "glorious boy" and was disappointed when Lady Byron gave birth to a girl.

She valued metaphysics as much as mathematics, viewing both as tools for exploring "the unseen worlds around us." ===Death=== Lovelace died at the age of 36 on 27 November 1852, from uterine cancer probably exacerbated by bloodletting by her physicians.

1953

The engine was never completed so her program was never tested. In 1953, more than a century after her death, Ada Lovelace's notes on Babbage's Analytical Engine were republished as an appendix to B.V.

1980

The reference manual for the language was approved on 10 December 1980 and the Department of Defense Military Standard for the language, MIL-STD-1815, was given the number of the year of her birth. In 1981, the Association for Women in Computing inaugurated its Ada Lovelace Award.

1998

Since 1998, the British Computer Society (BCS) has awarded the Lovelace Medal, and in 2008 initiated an annual competition for women students.

2002

Her work was well received at the time; the scientist Michael Faraday described himself as a supporter of her writing. The notes are around three times longer than the article itself and include (in Note G), in complete detail, a method for calculating a sequence of Bernoulli numbers using the Analytical Engine, which might have run correctly had it ever been built (only Babbage's Difference Engine has been built, completed in London in 2002).

2008

Since 1998, the British Computer Society (BCS) has awarded the Lovelace Medal, and in 2008 initiated an annual competition for women students.

2009

Ada College is a further-education college in Tottenham Hale, London, focused on digital skills. Ada Lovelace Day is an annual event celebrated on the second Tuesday of October, which began in 2009.

2013

Ada Lovelace House is a council-owned building in Kirkby-in-Ashfield, Nottinghamshire, near where Lovelace spent her infancy. In 2013 Ada Developers Academy was founded and named after her.
