1900 – 1958
Wolfgang Pauli (1900–1958) was an Austrian-Swiss theoretical physicist and one of the founders of quantum mechanics. Best known for the Pauli exclusion principle, he made foundational contributions to quantum field theory, spin theory, and the theoretical basis of modern physics.
Formulated the Pauli exclusion principle (1925), foundational to quantum mechanics and atomic structure
Predicted the existence of the neutrino (1930) to account for energy conservation in beta decay
Developed the theory of spin and the Pauli matrices in quantum mechanics
Contributed to relativistic quantum field theory and the spin-statistics theorem
Explored foundations of physics including the role of measurement and spacetime structure in relativity
