  • Alan Turing
    Alan Mathison Turing (; 23 June 1912 – 7 June 1954) was an English mathematician, computer scientist, logician, cryptanalyst, philosopher and theoretical biologist. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence. Despite these accomplishments, he was not fully recognised in his home country during his lifetime, due to his homosexuality, and because much of his work was covered by the Official Secrets Act. During the Second World War, Turing worked for the Government Code and Cypher School (GC&CS) at Bletchley Park, Britain's codebreaking centre that produced Ultra intelligence. For a time he led Hut 8, the section that was responsible for German naval cryptanalysis. Here, he devised a number of techniques for speeding the breaking of German ciphers, including improvements to the pre-war Polish bombe method, an electromechanical machine that could find settings for the Enigma machine. Turing played a pivotal role in cracking intercepted coded messages that enabled the Allies to defeat the Nazis in many crucial engagements, including the Battle of the Atlantic, and in so doing helped win the war. Due to the problems of counterfactual history, it's hard to estimate what effect Ultra intelligence had on the war, but at the upper end it has been estimated that this work shortened the war in Europe by more than two years and saved over 14 million lives.After the war, Turing worked at the National Physical Laboratory, where he designed the Automatic Computing Engine, which was one of the first designs for a stored-program computer. In 1948, Turing joined Max Newman's Computing Machine Laboratory at the Victoria University of Manchester, where he helped develop the Manchester computers and became interested in mathematical biology. He wrote a paper on the chemical basis of morphogenesis and predicted oscillating chemical reactions such as the Belousov–Zhabotinsky reaction, first observed in the 1960s. Turing was prosecuted in 1952 for homosexual acts; the Labouchere Amendment of 1885 had mandated that "gross indecency" was a criminal offence in the UK. He accepted chemical castration treatment, with DES, as an alternative to prison. Turing died in 1954, 16 days before his 42nd birthday, from cyanide poisoning. An inquest determined his death as a suicide, but it has been noted that the known evidence is also consistent with accidental poisoning. In 2009, following an Internet campaign, British Prime Minister Gordon Brown made an official public apology on behalf of the British government for "the appalling way he was treated". Queen Elizabeth II granted Turing a posthumous pardon in 2013. The Alan Turing law is now an informal term for a 2017 law in the United Kingdom that retroactively pardoned men cautioned or convicted under historical legislation that outlawed homosexual acts.On 15 July 2019 the Bank of England announced that Turing would be depicted on the United Kingdom's new £50 note.

It was announced in January 2017 that she would step down from the company's board upon the sale of Yahoo!'s operating business to Verizon Communications for $4.8 billion. She would not join the newly combined company, now called Verizon Media (formerly Oath), and announced her resignation on June 13, 2017. She is a graduate of Stanford University and was a long-time executive, usability leader, and key spokeswoman for Google (employee #20).
  • Larry Page
    Lawrence Edward Page (born March 26, 1973) is an American computer scientist and Internet entrepreneur who co-founded Google with Sergey Brin.Page is the chief executive officer of Alphabet Inc. (Google's parent company). After stepping aside as Google CEO in August 2001, in favor of Eric Schmidt, he re-assumed the role in April 2011. He announced his intention to step aside a second time in July 2015, to become CEO of Alphabet, under which Google's assets would be reorganized. Under Page, Alphabet is seeking to deliver major advancements in a variety of industries.As of June 2019, Page is the 12th-richest person in the world, with a net worth of $51.1 billion. Forbes placed him 10th in the list "Billionaires 2019". Page is the co-inventor of PageRank, a well-known search ranking algorithm for Google, which he wrote with Brin. Page received the Marconi Prize in 2004 with Brin.
  • Sergey Brin
    Sergey Mikhaylovich Brin (Russian: Серге́й Миха́йлович Брин; born August 21, 1973) is an American computer scientist and Internet entrepreneur. Together with Larry Page, he co-founded Google. Brin is the president of Google's parent company Alphabet Inc. As of June 2019, Brin is the 13th-richest person in the world, with an estimated net worth of US$50.1 billion.Brin immigrated to the United States with his family from the Soviet Union at the age of 6. He earned his bachelor's degree at the University of Maryland, College Park, following in his father's and grandfather's footsteps by studying mathematics, as well as computer science. After graduation, he enrolled in Stanford University to acquire a PhD in computer science. There he met Page, with whom he built a web search engine. The program became popular at Stanford, and they suspended their PhD studies to start up Google in Susan Wojcicki's garage in Menlo Park.
  • Steve Wozniak
    Stephen Gary "Woz" Wozniak (; born August 11, 1950) is an American inventor, electronics engineer, programmer, philanthropist, and technology entrepreneur. In 1976 he co-founded Apple Inc., which later became the world's largest information technology company by revenue and largest company in the world by market capitalization. He and Apple co-founder Steve Jobs are widely recognized as two prominent pioneers of the personal computer revolution of the 1970s and 1980s. In 1975, Wozniak started developing the Apple I into the computer that launched Apple when he and Jobs first began marketing it the following year. He primarily designed the Apple II in 1977, known as one of the first highly successful mass-produced microcomputers, while Jobs oversaw among other things the development of its foam-molded plastic case and early Apple employee Rod Holt developed the switching power supply. With computer scientist Jef Raskin, Wozniak had major influence over the initial development of the original Apple Macintosh concepts from 1979 to 1981, when Jobs took over the project following Wozniak's brief departure from the company due to a traumatic airplane accident. After permanently leaving Apple in 1985, Wozniak founded CL 9 and created the first programmable universal remote, released in 1987. He then pursued several other business and philanthropic ventures throughout his career, focusing largely on technology in K–12 schools.As of January 2018, Wozniak has remained an employee of Apple in a ceremonial capacity since stepping down in 1985.
  • Ada Lovelace
    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. She was the first to recognise that the 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 sometimes regarded as the first to recognise the full potential of a "computing machine" and one of the first computer programmers.Lovelace was the only legitimate child of poet Lord Byron and his wife Lady Byron. All of Byron's other children were born out of wedlock to other women. Byron separated from his wife a month after Ada was born and left England forever four months later. He commemorated the parting in a poem that begins, "Is thy face like thy mother's my fair child! ADA! sole daughter of my house and heart?". He died of disease in the Greek War of Independence when Ada was eight years old. Her mother remained bitter and promoted Ada's interest in mathematics and logic in an effort to prevent her from developing her father's perceived insanity. Despite this, Ada remained interested in Byron. Upon her eventual death, she was buried next to him at her request. Although often ill in her childhood, Ada pursued her studies assiduously. She married William King in 1835. 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. Ada described her approach as "poetical science" and herself as an "Analyst (& Metaphysician)".When she was a teenager, her mathematical talents led her to a long working relationship and friendship with fellow British mathematician Charles Babbage, who is known as "the father of computers". She was in particular interested in Babbage's work on the Analytical Engine. 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. These notes contain what many consider to be the first computer program—that is, an algorithm designed to be carried out by a machine. 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. Lovelace's notes are important in the early history of computers. She also developed a vision of the capability of computers to go beyond mere calculating or number-crunching, while many others, including Babbage himself, focused only on those capabilities. 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.
