Dirac developed a equation of motion for the wavefunction of the electron based on relativity. Dirac to predicted the existence of the positron, the electron's antiparticle, which was subsequently discovered by Carl Anderson in 1932 AD. Dirac was the founder of quantum electrodynamics.

Dirac's published a famous textbook known as the "Principles of Quantum Mechanics" (1930 AD).  This book introduced the widely used delta function and [[bracket notation]].  Inspired in part by this book, physicist Richard Feynman later proposed a path integral formulation of quantum mechanics in 1948 AD.
