In Memory of Julian Schwinger

Although he was the recipient of a Nobel Prize and despite the greatness of his accomplishments, Julian Schwinger is almost an unsung hero of our age . He is relatively unknown to the general population, even though in the physics community he was a renowned theoretician and teacher of physics. He shared the 1965 Nobel Prize in physics with Richard P. Feynman and Shin'ichiro Tomonaga for their development of Quantum Electrodynamics (QED). Of these three extraordinary physicists, and even of all the physicists that worked on QED, his work was the most rigorous and mathematically exacting.
