I never had the good fortune of meeting Arthur Wightman in person, nor of attended any talks by him. But when I was teaching quantum field theory for the first time as a junior faculty member, I went thru his proof (with Arthur Jaffe) of the Parity-Charge-Time conjugation theorem, and the related Spin-Statistics Theorem---- one of the great marvels of fundamental physics, and of foundational Algebraic Quantum Field Theory. We remain indebted to his seminal contributions to C*-algebras-- and their many descendants, as theoretical particle physicists, and as string/M theorists. My condolences to his family and friends.
