Johann Baptist Großschedl von Aicha (5 February 1577 – 1630s) was a German nobleman, alchemist and esoteric author. The German "von Aicha" is a later supposition from the Latin "ab Aicha" on his publications, which may be related to
Aiglsbach in Bavaria and the "Grossehedl von Perckhausen und Aiglspach" nobility, who originally came from
Regensburg.
