Amman was born in Zurich, the son of a professor of Classics and Logic. He was himself well-educated. Little of his personal history is known beyond the fact that he moved to Nuremberg in 1560, where he continued to reside until his death in March 1591. He worked initially with Virgil Solis, then a leading producer of book illustrations. His productiveness was very remarkable, as may be gathered from the statement of one of his pupils, that the drawings he made during a period of four years would have filled a hay wagon. A large number of his original drawings are in the Berlin print room. About 1,500 prints are attributed to him. He was one of the last major producers of woodcuts for books, as during his career engravings were gradually taking over that role. Although like most artists for woodcut he normally let a specialist formschneider cut the block to his drawing, he sometimes included both a cutter's knife and a quill pen in his signature on prints, suggesting he sometimes cut his own blocks.
A series of engravings by Amman of the kings of France, with short biographies, appeared in Frankfurt in 1576. He also executed many of the woodcut illustrations for the Bible published at Frankfurt by Sigismund Feierabend. Another serial work, the Panoplia Omnium Liberalium Mechanicarum et Seden-tariarum Artium Genera Continens, containing 115 plates, is of great value. Amman's drawing is correct and spirited, and his delineation of the details of costume is minute and accurate. Paintings in oil and on glass are attributed to him, but none have been identified.
