When someone asks you �What's new?� have you ever considered responding � �c  over  lambda!�    To the chemist and physicist, such a play on words suggests an understanding of the concepts of quantum theory.  An equal response to  �What's nu?� might be   �E  over   h.�  These and many other theoretical principles are expressed on postage stamps and philatelic materials issued by .many nations of the world.  This presentation will attempt to weave a thread between individuals and their respective contributions to Quantum Theory.
