Stuart Ross Taylor, Leonard Medalist (1998) and former president of the Meteoritical Society (1989-1990) passed away at his home in Canberra, Australia, this month. Ross was a geochemist who made seminal contributions to our understanding of the origin and evolution of Earth’s continental crust, and the composition and origin of the Moon, meteorites, tektites, and the solar system. Born in Ashburton, New Zealand in 1925, he received a BSc and MSc Hons from the University of New Zealand followed by a PhD in 1954 at the University of Indiana, USA, where he studied under fellow Kiwi Brian Mason. Taylor was Mason’s only PhD student and Mason himself was the last PhD student of Victor Moritz Goldschmidt. Following his PhD, Ross became a tenured lecturer at Oxford University where he worked with Louis Ahrens and built an emission spectroscopy laboratory. More…
