About Franz Ernst Neumann
Franz Ernst Neumann was a German mineralogist and physicist. He devised the first formulas to calculate inductance. He also formulated Neumann's law for molecular heat. In electromagnetism, he is credited for introducing the magnetic vector potential. Bernhard Minnigerode (1837–1896), another student of Neumann, first expressed this relation in written form in 1887 in the journal Neues Jahrb. With the mathematician Carl Gustav Jacobi, he founded in 1834 the Mathematisch-physikalisches Seminar which operated in two sections for mathematics and for mathematical physics.
