André-Jean-François-Marie Brochant de Villiers (August 6, 1772 – May 16, 1840) was a
French mineralogist and
geologist.
He was born at the Château de Villiers, near
Mantes-la-Ville. After studying at the
École Polytechnique, Paris, he was in 1794 the first pupil admitted to the
École des Mines. In 1804 he was appointed professor of geology and mineralogy in the École des Mines, which had been temporarily transferred to
Pezay in
Savoy, and he returned with the school to Paris in 1815. Later on he became inspector general of mines and a member of the
Academy of Sciences.
He investigated the
transition strata of the
Tarantaise, wrote on the position of the
granite rocks of
Mont Blanc, and on the lead minerals of
Derbyshire and
Cumberland. He was charged with overseeing the construction of the geological map of France, undertaken by his pupils
Dufrénoy and
Elie de Beaumont.
His publications include
Traité élémentaire de minéralogie (2 vols., 1801–1802; 2nd ed., 1808), and
Traité abrégé de cristallographie (Paris, 1818).
