Johann Christian Poggendorff (29 December 1796 – 24 January 1877) was a German physicist born in Hamburg. Poggendorff is best known for his work related to electricity and magnetism, most notably the electrostatic motor which is analogous to Wilhelm Holtz's electrostatic machine. In 1841 he described the use of the potentiometer for measurement of electrical potentials without current draw.
