Wolfgang Pauli (25 April 1900 - 15 December 1958) was an Austrian-born theoretical physicist and one of the central builders of modern quantum mechanics. He is best known for the Pauli exclusion principle, which states that no two identical fermions in a quantum system can occupy the same quantum state. The principle became essential for understanding atomic structure, chemical periodicity, electron shells, and the stability of matter.

Pauli studied under Arnold Sommerfeld in Munich and quickly became known for his sharp criticism and command of the new quantum theory. His early review article on relativity was admired by Albert Einstein, while his later work helped clarify angular momentum, electron spin, and the algebraic language used in quantum theory. In 1930 he proposed the neutrino as a way to preserve energy conservation in beta decay, an idea later confirmed experimentally.

Quantum physics

Pauli's exclusion principle links the abstract structure of quantum states with observable matter. It explains why electrons fill atomic orbitals in ordered shells and why fermionic matter resists collapse. His work is therefore closely connected with atomic structure, multi-electron atoms, and particles and matter.

Pauli also contributed to the spin-statistics connection, which relates half-integer spin to fermionic antisymmetry. This connection is one of the conceptual bridges between nonrelativistic quantum mechanics and quantum field theory.
