“Ceci n’est pas le chat de Schrodinger, ceci est le chat de Piron.” (C. Piron)
Bob Coecke (Oxford) writes:
“It is with sadness that I report that Constantin Piron, famous for many things including the Jauch-Piron NoGo-theorem and his reconstruction theorem, and of course his beautiful book Foundations of Quantum Physics, has died at the age of 80. While usually associated with quantum logic, he strongly emphasized an operational underpinning of axiomatic concepts, and boldly went against any dogma, including quantum logic. He was probably the most colorful, entertaining, and especially the boldest scientist I ever have met, in many ways.”
Piron did his PhD (Lausanne 1963) on axiomatic quantum theory under the supervision of Josef-Maria Jauch and Ernst Stueckelberg, two other giants of the Swiss school on the foundations of quantum mechanics. For some anecdotes not illustrating Piron’s work, but his human side, go to this website. I have noticed, with shock, that there exists no Wikipedia page on him, at least not in English. Anybody who has reliable information about him is hereby invited to change this! Also, please feel free to comment on this post.
