The Little Masters ("Kleinmeister" in German), were a group of German printmakers who worked in the first half of the 16th century, primarily in engraving. They specialized in very small finely detailed prints, some no larger than a postage stamp. The leading members were Hans Sebald Beham, his brother Barthel, and George Pencz, all from Nuremberg, and Heinrich Aldegrever and Albrecht Altdorfer. Many of the Little Masters' subjects were mythological or Old Testament stories, often treated erotically, or genre scenes of peasant life. The size and subject matter of the prints shows that they were designed for a market of collectors who would keep them in albums, of which a number have survived.
The term "Kleinmeister" was used of the Nuremberg Little Masters as early as 1679, by Joachim von Sandrart, and has been applied to other groups of artists, from the genre masters of the Dutch Golden Age to a group of 6th-century BC Ancient Greek vase-painters.
The earliest artist to make very small intricate engravings was Altdorfer in 1506–7, probably following the example of Italian niello prints, although their size was in fact no smaller than the bottom end of the very cheap devotional woodcuts made throughout the 15th century. However Altdorfer's printmaking developed in different directions, though he continued to produce some small engravings until the 1520s, by which time the style had been taken up by the Nuremberg artists, the Beham brothers and their close friend Pencz.
Hans Sebald Beham and Pencz continued to produce engravings until shortly before their deaths in 1550, which effectively ended the style; Barthel Beham had died in 1540. Barthel is generally considered the most inventive of the Nuremberg trio, but his brother Sebald was much more productive, with perhaps the finest technique, and also copied some of Barthel's prints after his death. Aldegrever was a convinced Lutheran who developed Anabaptist leanings, which perhaps led to him spending much of his time producing ornament prints with no human figures.
