Erhardus Ratdolt (1442–1528) was a German printer working in Venice during the years 1476 to 1486. In May of 1482, he published the first printed edition of Euclid’s *Elements, Euclid* *Liber elementorum in artem geometrie*. Its contents were based on the medieval translation of the work from Greek to Latin by Campanus (circa 1220-1296). In the process of producing this book, Ratdolt solved the problem of printing geometric diagrams. He is considered the first printer of scientific works and was known for his innovative typography. This edition of Euclid’s *Elements* remains today a masterpiece of mathematical printing.
