LACROIX, ANTOINE FRANÇOIS ALFRED (1863–  ), French mineralogist and geologist, was born at Mâcon, Saône et Loire, on the 4th of February 1863. He took the degree of D. ès Sc. in Paris, 1889. In 1893 he was appointed professor of mineralogy at the Jardin des Plantes, Paris, and in 1896 director of the mineralogical laboratory in the École des Hautes Études. He paid especial attention to minerals connected with volcanic phenomena and igneous rocks, to the effects of metamorphism, and to mineral veins, in various parts of the world, notably in the Pyrenees. In his numerous contributions to scientific journals he dealt with the mineralogy and petrology of Madagascar, and published an elaborate and exhaustive volume on the eruptions in Martinique, La Montagne Pelée et ses éruptions (1904). He also issued an important work entitled Mineralogie de la France et de ses Colonies (1893–1898), and other works in conjunction with A. Michel Lévy. He was elected member of the Académie des sciences in 1904.
