Christoph Heinrich Pfaff

Christoph Heinrich Pfaff (2 March 1773, Stuttgart – 24 April 1852, Kiel, Holstein) was a German physician, chemist and physicist.

He graduated as a physician at the Karlsschule in Stuttgart in 1793, where he studied under Carl Friedrich Kielmeyer and became good friends with Georges Cuvier.

[1] He then went to Göttingen, where he published the results of his galvanic inquiries in Ueber thierische Electricität und Reizbarkeit ("On animal electricity and susceptibility to stimulus").

[2] He then directed his attention particularly to pharmaceutical chemistry, and was thus led to the composition of his most important work, System der Materia Medica nach chemischen Principien ("System of materia medica using chemical principles", 1808–24).
