Charles Eugène de Foucauld was a cavalry officer in the French Army, then an explorer and geographer, and finally a Catholic priest and hermit who lived among the Tuareg in the Sahara in Algeria. He was assassinated in 1916 and is considered by the Church to be a martyr. His inspiration and writings led to the founding of the Little Brothers of Jesus among other religious congregations.
Orphaned at the age of six, Charles de Foucauld was brought up by his maternal grandfather, Colonel Beaudet de Morlet. He joined the Saint-Cyr Military Academy. Upon leaving the Academy he opted to join the cavalry.
