The significant contributions of Evariste Galois (1811-1832) to the foundation of group theory were not widely recognized until many years after his untimely death in a duel in 1832. On the eve of his death he entrusted a resume of the mathematical ideas and writings that occopied his mind, including the discovery of the connection of the theory of groups with the solution of equations by radicals, to his friend Auguste Chevalier. Not until 1846 were these collected writings published by Liouville in th e Journal de Mathematiques Pures et Appliquees.
