The world has sadly lost a renowned mathematical genius, John Horton Conway, who passed away at the age of 82 in Princeton, New Jersey on April 11th, 2020 after a long illness. John was born on December 26th, 1937 in Liverpool, England, and grew up in a family of mathematicians and artists. He earned his B.A. in Mathematics from the University of Cambridge in1959 and his Ph.D. in Mathematics from the University of Cambridge in 1964. John was best known as the inventor of the Game of Life, a cellular automaton which simulates the life cycle of a living organism, and for his work in developing an algebraic representation of knots, which led to the invention of surreal numbers. He was also a professor of mathematics and a professor emeritus of Princeton University. John positively impacted the mathematical community as an active member from the time he was a student at Cambridge and was a considerable influence on friends and colleagues. He was awarded many awards in his lifetime, including the Leroy P. Steele Prize for Mathematical Exposition in 1990, the Wolf Prize in Mathematics in 2002, the Order of the British Empire in 2005, the Abel Prize in 2020, and many others. He was also given the nickname “The Genius of Princeton.” John will be sadly missed by all who knew him, and fondly remembered for his boundless intelligence and creativity.
