Wolfgang Pauli

Wolfgang Pauli was an Austrian-born physicist awarded the 1945 Nobel Prize in Physics for his discovery of the Pauli exclusion principle, that no two fermions in a system can have the same four quantum numbers. In terms of the atom, this means that at most two electrons may occupy the same orbital (the two having opposite spin).
