Albrecht D黵er (German: 21 May 1471 - 6 April 1528) was a German painter; engraver; printmaker; mathematician; and theorist from Nuremberg. His high-quality woodcuts (nowadays often called Meisterstiche or 'master prints') established his reputation and influence across Europe when he was still in his twenties; and he has been conventionally regarded as the greatest artist of the Northern Renaissance ever since.

His vast body of work includes altarpieces and religious works; numerous portraits and self-portraits; and copper engravings. The woodcuts; such as the Apocalypse series (1498); retain a more Gothic flavour than the rest of his work. His well-known prints 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.

D黵er'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
