Martin Ohm

He earned his doctorate in 1811 at Friedrich-Alexander-University, Erlangen-Nuremberg where his advisor was Karl Christian von Langsdorf.

[1] In 1817, he was appointed professor of mathematics and physics in the gymnasium at Thorn.

[2] Ohm was the first to fully develop the theory of the exponential ab when both a and b are complex numbers in 1823.

[3][4] It was via sources relying on Ohm that the psychologist Adolf Zeising adopted and popularised the term.

Ohm's students included Friedrich August, Friedrich Bachmann, Elwin Bruno Christoffel, Paul Bachmann, Joseph Brutkowski, Heinrich Eduard Heine, Rudolf Lipschitz, Leo Pochhammer, Friedrich Prym, Wilhelm Wagner, Hermann Waldaestel, Wilhelm Wernicke, Elena Gerz, Valentien Gerz, and Johanna Gerz.
