Abstract: The experimental observations that led to the development of hadron physics are reviewed with emphasis on the discoveries of mesons and baryons, starting in the 1940s with the pion and kaon which mediate the strong hadronic force. The evidence for an internal structure consisting of two or three elementary spin 1/2 particles will be reviewed. In 2003 more complex multi-quark hadrons began to emerge. The subsequent developments beyond the early 2000s are covered in the Review of Particle Physics (Int. J. Mod. Phys. A 41 (2026) 2630011). Given the large number of hadrons, the choice of key experiments is somewhat subjective.
