The works of Hodler's early maturity consisted of landscapes, figure compositions, and portraits, treated with a vigorous realism. In 1884, Hodler met Augustine Dupin (1852–1909), who became his companion and model for the next several years. Their son, Hector Hodler—who would found the World Esperanto Association in 1908—was born in 1887.
