Le Behemoth first came to notice in MC circles when he entered the newly-formed French National Championship in 1909.  During a meteoric rise to international grandmaster status, Le Behemoth participated in every possible European title in the five years leading up to World War I.  His style of play is said to have contributed something to the intensity of the hostilities.
