Max Euwe (May 20, 1901 - Nov 26, 1981) was the greatest chess talent ever to come out of the Netherlands and the 5th World Champion. Both of his parents loved chess and taught Max to play when he was very young. He grew up with chess as an integral part of his life.
He was one of the last great chess players of the amateur era. Chess was a pastime, not a career. If he would have dedicated his life absolutely to chess in the same way as some of his contemporaries, maybe he would have had more than two years as World Champion, following his victory over
Alexander Alekhine. If anything, winning the World Championship as a part-timer against dedicated professionals should make him all the more respected.
Euwe was also a prolific chess author, turning out 70 chess books over the years. He made huge contributions to opening theory. He was also FIDE President for most of the 1970s. His main achievement in this time was to make sure the Match of the Century in 1972 went ahead.
