Paul Petrovich Keres was born in 1916 in Estonia, where he would reside his entire life. He was very active in correspondence chess throughout his youth, and soon began to make a name for himself at over-the-board play as well with a series of tournament victories culminating with a win at AVRO 1938. In 1948, Keres participated in the World Championship tournament to determine a successor to Alexander Alekhine. He finished joint third. He suffered a fatal heart attack on the way home from a tournament in Vancouver in 1975, at the age of fifty-nine. (source : chessgames.com)
