Johann Heinrich Schulze, ca 1727, by Haid
Johann Heinrich Schulze (12 May 1687 – 10 October 1744) was a German professor and polymath from Colbitz in the Duchy of Magdeburg. Schulze studied medicine, chemistry, philosophy and theology and became a professor in Altdorf and Halle for anatomy and several other subjects. Schulze is best known for his discovery that the darkening in sunlight of various substances mixed with silver nitrate is due to the light, not the heat as other experimenters believed, and for using the phenomenon to temporarily capture shadows.
