LGBTQ+ Pride Month: Turing Honored on British Bill

June is LGBTQ+ Pride Month. All month long, Behind the Headlines will feature lesbian, gay, bisexual, transgender, and queer or questioning pioneers in a variety of areas.

On what would have been his 109th birthday, the English mathematician, computer pioneer, and codebreaker Alan Turing is getting a very special gift: a 50-pound (£50) note. It’s not just an old £50 bank note, however. This bank note—and millions of others—will have his face on it.

Following a public nomination process in 2019, Turing was selected to be the new face of the £50 note. His image will replace images of the engineer and scientist James Watt and the industrialist and entrepreneur Matthew Boulton. An image of Elizabeth II will remain on the obverse side of the note, or the side that bears the principal design.

Turing was recognized not only for his important contributions to the development of electronic digital computers, but also for the discrimination he faced as a gay man. After World War II (1939-1945), Turing was prosecuted for his relationship with a man. He was given the choice of either imprisonment or probation with the condition of undergoing female hormone treatment. On June 7, 1954, at the age of 41, Turing took his own life.

In 2009, the British government issued an apology. Four years later, Turing was given a royal pardon, releasing him for the legal penalties for his crime. In 2017, the Turing Law was passed, which pardoned thousands of gay and bisexual men who had been convicted of sexual offenses that have since been eliminated.

Turing was born on June 23, 1912, in London. He studied mathematics at Cambridge University and Princeton University. In 1936, he developed a hypothetical computing machine—now called the Turing machine—that could, in principle, perform any calculation. The device had a long tape divided into squares on which symbols could be written or read. The tape head of the machine could move to the left or to the right. The machine also had a table to tell it the order in which to carry out operations. The Turing machine became an important model for determining what tasks a computer could perform. During World War II, Turing helped crack German codes.

After the war, he worked on a project to build the first British electronic digital computer. In 1950, he proposed a test for determining if machines might be said to “think.” This test, now called the Turing test, is often mentioned in discussions of artificial intelligence (AI).

A. M. Turing Award

Thursday, April 5th, 2018

April 5, 2018

It can be easy to forget how much computer innovations have changed and improved our everyday lives over the years. A person living 100 years ago would scarcely be able to imagine sending a message directly to someone on the opposite side of the globe with just the click of a button or having access to an entire encyclopedia of information from a small handheld device. We have these and many more luxuries thanks to several decades of computing innovations. Fifty years ago, the Association for Computing Machinery (ACM) in New York City introduced the annual A. M. Turing Award to honor the hardworking computer scientists behind those innovations.

The A. M. Turing Award is given to one or more individuals each year in recognition of contributions of lasting importance in the field of computing. On March 21, 2018, the American computer scientists David A. Patterson and John L. Hennessy were named the recipients of the 2017 A. M. Turing Award for their pioneering work in computer chip design. The two men are responsible for designing and promoting reduced instruction set computer (RISC) microprocessors. A microprocessor is a kind of computer chip that carries out the instructions that make up computer programs. RISC microprocessors are simplified computer chips that run faster and consume less power than other kinds of chips.

Patterson proposed the idea for a RISC computer in 1980. He and his research team at the University of California in Berkeley built and demonstrated the first RISC processor in 1982. Hennessy’s research team at Stanford University in California developed further RISC models shortly thereafter. In 1990, Patterson and Hennessy co-wrote a groundbreaking textbook on microprocessor design. The book, called Computer Architecture: A Quantitative Approach, became a standard text for engineering computer chips. Today, about 99 percent of all microprocessors produced annually are RISC processors. RISC chips are found in almost every smartphone and tablet.

The A. M. Turing Award is named after Alan Mathison Turing, a British mathematician and computer pioneer. Turing made key contributions to the development of electronic computers, including his work helping to build the first British electronic digital computer. In 1950, he proposed a test for determining if machines might be said to “think.” This test, now called the Turing test, is still central to discussions of artificial intelligence.

The first Turing Award was given to the American computer scientist Alan J. Perlis in 1966 for his role in developing influential computer-programming techniques. Since then, an award has been given every year. As of 2014, the award includes a $1 million cash prize.
