Johann Albrecht Widmannstetter, also called Widmannstadt, Johannes Albertus Widmanstadius or Widmestadius, (1506 in Nellingen/Blaubeuren near Ulm – March 28, 1557 in Regensburg), was a German humanist, orientalist, philologist, and theologian.
Widmannstetter studied law, theology and oriental languages in Tübingen. After 1527, he continued his studies in Italy, in Turin, Naples and Rome, focusing on Syrian and Arabian. In 1533, Widmannstetter became secretary to pope, Pope Clement VII. In the same year, he delivered a series of lectures in Rome, outlining Nicolaus Copernicus' theory to the pope and the cardinals, with which both were impressed.
Pope Clement VII died in 1534, and was succeeded by Pope Paul III; Widmannstetter continued as his secretary.
After 1535, Widmannstetter was secretary of Cardinal Nikolaus von Schönberg. Impressed by Widmannstetter's lessons on Copernicus' ideas, the Cardinal wrote a letter to Copernicus in 1536, urging him to publish (which he would do only in 1543, shortly before his death).
The rest of Widmanstetter's career was focussed on orientalism, to which he contributed a great deal, collecting hundreds of manuscripts in Hebrew, Arabic and Syriac. Widmannstetter is considered to be a founder of European orientalism.
