Marc Theodore Bourrit, a Swiss artist and author, born in Geneva about 1739, died near that city about 1815. He early evinced artistic talent, and reproduced the beauties of Alpine scenery in remarkable descriptions and illustrations, while gaining a livelihood as a chorister. Victor Amadeus of Sardinia and Louis XVI. became his patrons, and' the latter gave him a pension. At the instance of Buffon, who had presented him to the French monarch, he took up his residence in Paris. After repeated unsuccessful attempts to ascend Mont Blanc with De Saussure, he succeeded in reaching the summit in 1787. He was remarkable for generosity and courage, once at great risk saving Prince Galitzin, then unknown to him, from drowning. His principal works are: Description des Alpes pennines et rlietiennes (2 vols., Geneva, 1781); new edition, comprising also Nouvelle description des glacieres et glaciers de la Savoie, par-ticulierement de la vallee de Ghamouny et du Mont Blanc (3 vols., 1787); and Description des cols et passages des Alpes (2 vols., 1803).
