The great mathematician Leonhard Euler ➚ is the man chiefly credited with the creation of the puzzle that we now know as Sudoku. Born in Basle,Switzerland ➚ in 1707 just after the giant leap forward in mathematics pioneered by Isaac Newton ➚ and Gottfried Leibniz ➚, he both consolidated and pioneered mathematical knowledge in many fruitful areas. He moved from Basle to St Petersburg, Russia to study medicine but by the chance happenings of fate he became the chief mathematician at the St Petersburg Academy ➚. In 1741 he went to Germany for 25 years before returning to the Academy in Russia where he died at the grand age of 76. Even though blind for the last seventeen years of his life he still made important discoveries.
