Roger W.H. Sargent
Roger W.H. Sargent was Dean of the City and Guilds College from 1973 to 1976, Head of the Department of Chemical Engineering from 1975 to 1988 and Director of the Centre for Process Systems Engineering (which he founded) from its launch in August 1989 until he retired in 1992, when he became a Senior Research Fellow and Emeritus Professor in the Centre and a Foreign Associate of the US National Academy of Engineering.He is known principally as one of the earliest creators of the discipline of Process Systems Engineering, and his influence has been extremely widely spread among that community, by his research and also by his extraordinarily large family tree (Academic genealogy) of research students. In his career at Imperial College he supervised 43 research students, and several of these first-generation students have gone on to establish large research schools of their own. By 2008, this family tree extended to seven generations and 639 students and former students. His influence is commemorated in the annual "Roger Sargent" lectures at Imperial college, the 17th of which was held in December 2010 and which he attended.
