Famous French-speaking writers were Jean-Jacques Rousseau (1712–1778) and Germaine de Staël (1766–1817). More recent authors include Charles Ferdinand Ramuz (1878–1947), whose novels describe the lives of peasants and mountain dwellers, set in a harsh environment and Blaise Cendrars (born Frédéric Sauser, 1887–1961). Italian and Romansh-speaking authors also contributed to the Swiss literary landscape, but generally in more modest ways given their small number.
