Jan Łukasiewicz
In the early 1920s, the Polish mathematician Jan Lukasiewicz discovered that if operators were written before the operands (prefix or Polish notation; for example, + a b), the parentheses are not needed. He was born on 21 December 1878 in Lemberg, Galicia, Austria-Hungary and died on 13 February 1956 in Dublin, Ireland. He was aged 77.
