Albrecht Dürer was a German painter renowned for his graphic works and as an art theorist. As a teenager, Dürer apprenticed with his father to become a goldsmith. Shortly thereafter, Dürer also began to draw and created his first self-portrait in 1484. He later learned to make woodcuts, a method of reproducing images in large quantities. During his travels in the Netherlands and Italy, he found crucial inspiration concerning spatial perception and figure modeling through foreshortening. Dürer's drawings of proportions and diagrams for painting are recognized to this day and came to define most of his career. In 1495 Dürer founded his own studio in Nuremberg, which drew a large student following. Book illustrations and graphic works were produced here using copper engravings and woodcuts. In 1512 he was appointed court painter to Maximilian I and later to his successor, Charles V.
