IN MEMORIAM: Dr. An Tzu Yang (1923–2003)

Abstract

When applying for graduate school, I was contacted by Prof. A. T. Yang at UC Davis, but wound up at Stanford only to find decades later that my research is dominated by the mathematics of dual quaternions that Prof. Yang presented so clearly and completely to our community. Two years ago, I had the honor of describing this research, and the literally hundreds of millions of spatial linkages to which it applies, at a research symposium in honor of Prof. Yang’s 80th birthday. A month ago I attended his memorial service and was touched to hear of his adventurous spirit and love of basketball, cards, friends and family. It is a profound honor to be part of a community of scholarship with colleagues such as Professor An Tsu Yang.
