Jodocus Badius (French: Josse Bade; Spanish: Jodoco del Badia; 1462–1535), also known as Josse Badius, Jodocus van Asche Badius, and Badius Ascensius, was a pioneer of the printing industry, a renowned grammarian, and a pedagogue.
Josse Badius was born in the village of Asse (formerly Assche) near Brussels in Flemish Brabant in AD 1462. He was a scholar of considerable repute, studying in Brussels and Ferrara and teaching Greek for several years at Lyons, France. During the years 1492–1498, while in Lyon, he began working as a proofreader and editor for the printer Jean Trechsel.
He moved to Paris, where he established his own printing house in the year 1503, which eventually took the name Prelum Ascensianum. With 775 editions, it served as one of the most active publishers during the first three decades of the 16th century. He specialized in Roman classical texts in Latin, often with his own familiare commentum for the student market. For example, for the 2nd-century BC Roman playwright Terence, Badius printed a Praenotamenta in 1502. This introduced the subject of Roman comedy through a lengthy treatment of general theories of poetry and thorough discussion of its origins, development, and classifications. He also published work by contemporary humanist writers. He frequently worked with or for Johannes Parvus (Jean Petit), the era's most important bookseller and publisher.
Badius died in 1535. His work was continued by his 2nd son Conrad. His epitaph was written by his grandson Henry Stephanus. Conrad confessed to being a Huguenot and forced to flee to Calvinist Geneva in 1549.
