French lieutenant of artillery; born at Paris, 1868; died in Togbao, Sudan, in 1899. His father, a poor pedler, observing Solomon's capacity for learning, made the greatest sacrifices to give him a good education. Solomon successfully passed the competitive examination for the Ecole Polytechnique, whence he graduated as lieutenant of artillery. In 1897 he obtained permission from the minister of war to join the perilous expedition for the exploration of Lake Tchad under Major Bretonnet. The expedition was surprised, and every member slaughtered by the Tuaregs.
