Professor Duncan Dowson is considered the father of the science of tribology (friction, wear and lubrication) in the UK, having revolutionised the approach to, and the understanding of, significant aspects of the subject. His seminal work has enhanced understanding and spawned new developments and designs in areas as diverse as rotating machinery, internal combustion engines and bio-tribology – particularly natural and artificial human joints. Duncan was appointed Professor of Engineering Fluid Mechanics and Tribology in the University of Leeds in 1966. He served as Pro-Vice Chancellor and Head of Mechanical Engineering at Leeds and retired in 1993. He was President of the Institution of Mechanical Engineers in 1992.
