Johann Christian Wiegleb (December 21, 1732 – January 16, 1800) was a notable German apothecary and early innovator of chemistry as a science.

His numerous studies on the chemical nature of minerals were usually published in Lorenz von Crell’s Chemische Annalen.

[5] Wiegleb was a member of the Kurmainzische Academy of useful sciences and the Leopoldina.

It turned out that it was identical with sugar acid, which was discovered by Carl Wilhelm Scheele in 1784.

He conducted studies of alkaline salts in plants, on the combustion of chalk and argued against the possibility of transmutation of elements.
