Johann Heinrich WincklerJohann Heinrich Winckler was a German scholar of wide interests. He is perhaps best remembered as a physicist.
Winckler attended school in Lubań and went on to study in Leipzig. At the beginning of the 1730s he was a teacher (''collega quartus'') at the Thomasschule in Leipzig. In 1732 he wrote the libretto of ''Froher Tag, verlangte Stunde'', a cantata to mark the renovation of the school. It was set to music by his colleague Johann Sebastian Bach. By the end of the 1730s he was teaching at Leipzig University. Provided by Wikipedia
