D'ALEMBERT

D'ALEMBERT (1717-1783), a French philosopher, devoted to science, and especially to mathematics; along with Diderot established the celebrated "Encyclopédie," wrote the Preliminary Discourse, and contributed largely to its columns, editing the mathematical portion of it; trained to quiet and frugality, was indifferent to wealth and honour, and a very saint of science; no earthly bribe could tear him away from his chosen path of life.
