Rodolphus Agricola (Phrisius) (?February 17, 1444, August 28, 1443? – October 27, 1485) was a pre-Erasmian humanist of the northern Low Countries, famous for his supple Latin and one of the first north of the Alps to know Greek well. Agricola was a Hebrew scholar towards the end of his life, an educator, musician and builder of a church organ, a poet in Latin as well as the vernacular, a diplomat and a sportsman of sorts (boxing). He is best known today as the author of De inventione dialectica, as the father of northern European humanism and as a zealous anti-scholastic in the late-fifteenth century. Born at Baflo, in the Dutch province of Groningen, Agricola was originally named Roelof Huusman.
