Albrecht Dürer (/ˈdʊərər, ˈdjʊərər/; German: [ˈalbʁɛçt ˈdyːʁɐ]; 21 May 1471 – 6 April 1528) was a painter, printmaker and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe when he was still in his twenties, due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by emperor Maximilian I. His vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), retain a more Gothic flavour than the rest of his work. His well-known engravings include the Knight, Death, and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium. Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective and ideal proportions. Dürer was born on 21 May 1471, third child and second son of his parents, who had between fourteen and eighteen children. His father, Albrecht Dürer the Elder, was a successful goldsmith, originally Ajtósi, who in 1455 had moved to Nuremberg from Ajtós, near Gyula in Hungary. The German name "Dürer" is a translation from the Hungarian, "Ajtósi". Initially, it was "Türer," meaning doormaker, which is "ajtós" in Hungarian (from "ajtó", meaning door). A door is featured in the coat-of-arms the family acquired. Albrecht Dürer the Younger later changed "Türer", his father's diction of the family's surname, to "Dürer", to adapt to the local Nuremberg dialect. Albrecht Dürer the Elder married Barbara Holper, the daughter of his master, when he himself became a master in 1467. Dürer's godfather was Anton Koberger, who left goldsmithing to become a printer and publisher in the year of Dürer's birth and quickly became the most successful publisher in Germany, eventually owning twenty-four printing-presses and having many offices in Germany and abroad. Koberger's most famous publication was the Nuremberg Chronicle, published in 1493 in German and Latin editions. It contained an unprecedented 1,809 woodcut illustrations (albeit with many repeated uses of the same block) by the Wolgemut workshop. Dürer may well have worked on some of these, as the work on the project began while he was with Wolgemut. Because Dürer left autobiographical writings and became very famous by his mid-twenties, his life is well documented by several sources. After a few years of school, Dürer started to learn the basics of goldsmithing and drawing from his father. Though his father wanted him to continue his training as a goldsmith, he showed such a precocious talent in drawing that he started as an apprentice to Michael Wolgemut at the age of fifteen in 1486. A self-portrait, a drawing in silverpoint, is dated 1484 (Albertina, Vienna) "when I was a child," as his later inscription says. Wolgemut was the leading artist in Nuremberg at the time, with a large workshop producing a variety of works of art, in particular woodcuts for books. Nuremberg was then an important and prosperous city, a centre for publishing and many luxury trades. It had strong links with Italy, especially Venice, a relatively short distance across the Alps.
