Who Was Ada Lovelace?
Early Years
Ada Lovelace, born as Augusta Ada Byron on December 10, 1815, was the only legitimate child of the famous poet Lord George Gordon Byron. Lord Byron's marriage to Lovelace's mother, Lady Anne Isabella Milbanke Byron, was not a happy one. Lady Byron separated from her husband only weeks after their daughter was born.
Babbage and the Analytical Engine
Around the age of 17, Ada met Charles Babbage, a mathematician, and inventor. The pair became friends, and the much older Babbage served as a mentor to Lovelace. Through Babbage, Lovelace began studying advanced mathematics with University of London professor Augustus de Morgan.
Lovelace was fascinated by Babbage's ideas. Known as the father of the computer, he invented the difference engine, which was meant to perform mathematical calculations. Lovelace got a chance to look at the machine before it was finished, and was captivated by it. Babbage also created plans for another device known as the analytical engine, designed to handle more complex calculations.
Lovelace was later asked to translate an article on Babbage's analytical engine that had been written by Italian engineer Luigi Federico Menabrea for a Swiss journal. She not only translated the original French text into English but also added her own thoughts and ideas on the machine. Her notes ended up being three times longer than the original article. Her work was published in 1843, in an English science journal. Lovelace used only the initials "A.A.L.," for Augusta Ada Lovelace, in the publication.
In her notes, Lovelace described how codes could be created for the device to handle letters and symbols along with numbers. She also theorized a method for the engine to repeat a series of instructions, a process known as looping that computer programs use today. Lovelace also offered up other forward-thinking concepts in the article. For her work, Lovelace is often considered to be the first computer programmer.
Lovelace's article attracted little attention when she was alive. In her later years, she tried to develop mathematical schemes for winning at gambling. Unfortunately, her schemes failed and put her in financial peril. Lovelace died from uterine cancer in London on November 27, 1852. She was buried next to her father, in the graveyard of the Church of St. Mary Magdalene in Nottingham, England.
Personal Life
In 1835, Lovelace married William King, who became the Earl of Lovelace three years later. She then took the title of Countess of Lovelace. They shared a love of horses and had three children together. From most accounts, he supported his wife's academic endeavors. Lovelace and her husband socialized with many of the interesting minds of the times, including scientist Michael Faraday and writer Charles Dickens.
Lovelace's health suffered, however, after a bout of cholera in 1837. She had lingering problems with asthma and her digestive system. Doctors gave her painkillers, such as laudanum and opium, and her personality began to change. She reportedly experienced mood swings and hallucinations.
Legacy
Lovelace's contributions to the field of computer science were not discovered until the 1950s. Her notes were reintroduced to the world by B.V. Bowden, who republished them in Faster Than Thought: A Symposium on Digital Computing Machines in 1953. Since then, Ada has received many posthumous honors for her work. In 1980, the U.S. Department of Defense named a newly developed computer language "Ada," after Lovelace.
