He was appointed Professor of Mechanical Engineering at the University of Leeds in 1955, where he did research work on toothed gearing and on the mechanical behaviour of textile spindles. Seven years later he returned to Cambridge as Professor of Mechanics and set up research work on a number of aspects of damping machinery.
