Introduction (in Honor of Marcos Moshinsky)

Abstract

I had the opportunity and pleasure to be associated with Marcos Moshinsky in his days as a graduate student in Princeton. He impressed me at once as a fellow of unusual modesty and reticence. He also impressed me as a man who does not rest until he has gone to the bottom of the problem that kindled his interest, until he has found a convincing solution thereof and until he succeeded in communicating his conclusions in a way which rendered the access to them easy to the reader.
