Born at Fontenay-sous-Bois May 13, 1907. Student of Natural Science at the Sorbonne till the age of twenty-four, then enrolls at the Ecole des Beaux-Arts ( 1931-1934). There he met Georges Rohner. In 1936 he traveled in Italy ( Siena, Florence, Rome), and in Northern Spain. He worked at Bandol, in Brittany and in Ile-de-France. He was made prisoner in July 1940, but escaped from Germany in November of 1941. Humbolt was part of an austere group who, united under the name "Forces Nouvelles" in 1935, wanted a "return to drawing, a return to a craft conscientious of tradition, in fervent contact with Nature." In 1946 the Galerie Charpentier organized an exhibition of his Ouessant canvases. Humblot is essentially a landscape painter; Brittany and her ports have never ceased to inspire him..
