Social media users hurled criticism at Microsoft this week for what many thought was an AI-generated obituary for NBA player Brandon Hunter on its website MSN. The controversy began after the obituary -- which had a headline that read "Brandon Hunter useless at 42" written by "Editor" -- appeared on the Microsoft-owned platform after Hunter's death on Tuesday. The obituary goes on to refer to the former Boston Celtics and Orlando Magic player having been "handed away on the age of 42" and claimed he "performed in 67 video games over two seasons and achieved a career-high of 17 factors in a recreation in opposition to the Milwaukee Bucks in 2004." The post appeared to follow a similar format to a story on TMZ Sports, Futurism noted, "albeit with altered punctuation and a use of synonyms so liberal that the result is essentially incomprehensible." You can compare both the obituary containing the error and the TMZ Sports story here.

Daniel (Danny) Bobrow passed away peacefully at home with his wife Toni and daughters Kimberly and Deborah in Palo Alto, California, on March 20, 2017, having bravely fought a five-month battle with cancer. Danny was born to Ruth Gureasko Bobrow and Jacob Bobrow on November 29, 1935, in the Bronx, New York City. A gifted student, he attended Bronx High School of Science and went on to earn a BS from Rensselaer Polytechnic Institute, an MS from Harvard, and a PhD in Mathematics from Massachusetts Institute of Technology under the supervision of Marvin Minsky. His was one of the first MIT doctoral theses in Artificial Intelligence. A pioneer with a long and distinguished research career in Artificial Intelligence as a Research Fellow in the System Sciences Laboratory of the Palo Alto Research Center (PARC), he is remembered as a mentor, friend, and role model for many.

Mr Gregory was a pioneer of human psychology, and made significant advances in the fast-changing world of artificial intelligence. Born in London in 1923, he was the son of astronomer Christopher Gregory. Mr Gregory spent five years in the RAF during the Second World War, after being called up at the age of 18. After exhibiting obvious academic talent the RAF offered Mr Gregory a scholarship to study philosophy and experimental psychology at Downing College, Cambridge and after proving himself a successful scientist and inventor he moved to Edinburgh, where he took up a post as professor of bionics. There he co-founded the Department of Machine Intelligence and Perception, the first of its kind in the UK.

"I like to think that since I was about 19, I have studied human decision-making and problem-solving," Dr. Simon said in a Post-Gazette interview last fall. He earned a doctorate in political science at the University of Chicago in 1943 and took teaching positions at the Illinois Institute of Technology and the University of California, Berkeley, before joining the newly established industrial administration school at the Carnegie Institute of Technology.

Born in the vicarage in Lenham, Kent, he was the second of the parish priest's three children. He joined The Pilgrim's school, Winchester, in 1932 and became a senior chorister at the cathedral. Three years later, he won the top entrance scholarship to Winchester College, where his precocious talents in mathematics and music flourished. In 1941, he won a scholarship to Balliol College, Oxford, to read chemistry, but at the end of his first year also took part one of the music tripos, and was appointed Balliol organ scholar. In his second year, Christopher performed what Dr John Jones has described as "probably the greatest intellectual feat by a Balliol undergraduate ever": he proposed, with convincing arguments, the correct structure of the chemical compound diborane (B2H6) - a compound that defied contemporary chemical valency principles.

The American scientist Joshua Lederberg, who has died aged 82, won the 1958 Nobel prize in physiology or medicine for showing that bacteria can conjugate and exchange small strips of genetic material. Among the consequences of this was the realisation that antibiotic resistance can be passed around between bacteria, rather than emerging from selective breeding of resistant strains. This opened new paths in genetic research. He went on to a distinguished career in science policy, advising government committees and presidents, heading Rockefeller University and writing a Washington Post column on science and society. Lederberg's father was an orthodox rabbi - the family had come to New York from Palestine - who wanted Joshua to follow in his footsteps.

Born in South Africa, he was educated at the South African College High School, took a first degree at the University of Cape Town in 1934 and a doctorate in Mathematical Physics at the University of London in 1953. After a spell as demonstrator in physics at Cape Town, he emigrated to Britain. Prior to the outbreak of the Second World War, he undertook ionospheric research in Marconi's Wireless Telegraph Company, transferring to the Government's Telecommunications Research Establishment after the outbreak of hostilities to carry out research on radar. In 1941, he enlisted in the Royal Air Force Volunteer Reserve, leaving in 1943 to go to Aberdeen University to run a special degree course for radio officers under the wartime Hankey Scheme. After the war was over, he returned to industrial research, first until 1949 in Mullard's Radio Valve Company on microwave electronics and then on television and photo-electric tubes at EMI's Research Laboratories.

He made contributions of crucial international significance in three distinct fields of endeavour. During the second world war, he developed code-breaking techniques which led to effective automatic deciphering of German high-level ciphers. In the 1950s, he worked with Anne on pioneering techniques which were fundamental in the development of in vitro fertilisation. Donald subsequently became one of the founders of the field of artificial intelligence, an area to which he devoted the remainder of his academic career. It was within this field that I came to know Donald as an inspirational supervisor of my PhD at Edinburgh - not only insightful, forceful and even heroic, but possessing a wicked sense of humour.

The following correction was printed in the Guardian's Corrections and clarifications column, Wednesday April 11 2007 In the article below, the "whirring tapes" of IBM's latest computer in 1949 were an anachronism. Magnetic tape was first used to record computer data in 1951. In the mid-1950s, John Backus, who has died aged 82, led a team at IBM that created a revolutionary new way to communicate with early electronic computers. They invented Fortran, the first true programming language, and in doing so laid the foundations of today's multi-billion dollar software industry. During a long career at IBM, Backus continued to seek better methods of computer programming, but his enduring legacy is Fortran, the language that is still used today to solve complex scientific problems such as weather forecasting and aircraft design.
