Friedrich Hermann Hund (4 February 1896 – 31 March 1997) was a German physicist from Karlsruhe known for his work on atoms and molecules.

Hund worked with such prestigious physicists as Erwin Schrödinger, Paul Dirac, Werner Heisenberg, Max Born, and Walther Bothe.

At that time, he was Born's assistant, working with quantum interpretation of band spectra of diatomic molecules.

Hund made pivotal contributions to quantum theory - especially concerning the structure of the atom and of molecular spectra.

On the occasion of his 100th birthday, the book: Friedrich Hund: Geschichte der physikalischen Begriffe [History of Physical Concepts] (Heidelberg, Berlin, Oxford), Spektrum, Akademie Verlag 1996, ISBN 3-8274-0083-X was published.

[3] Friedrich Hund's work and interest in the history of science was also discussed intensely in an interview conducted by Klaus Hentschel and Renate Tobies.
