Louis Étienne Ravaz (1863 to 1937) was a French specialist in ampelography and one of the creators of modern viticulture. Born at Saint-Romain-de-Jalionas in Isère, he founded the grape research station of Cognac in 1892 and directed it for several years. He was professor of viticulture, and from 1919 director, at the National School of Agriculture of Montpellier. He contributed to the spread of American grape varieties in the regions hit by the phylloxera blight and investigated the diseases of the grapevine. With Pierre Viala he described the causes of the black rot disease of grapevine and founded the Revue de viticulture, and he published several works on viticulture. He is the taxon author, with Viala, of the fungus genus Guignardia, described in 1892.
