Winter, David A., 1930-2012

David A. Winter (PhD, PEng) was a distinguished professor emeritus at the University of Waterloo. He was a founding member of the Canadian Society for Biomechanics and its first Career Award winner. He was later awarded the Muybridge Medal of the International Society of Biomechanics (ISB) and the Lifetime Achievement Award of The Gait and Clinical Movement Analysis Society. Before becoming an academic, he served as an electrical officer with the Royal Canadian Navy on HMCS Nootka from 1952 to 1958. He completed his service at the rank of lieutenant commander. In December 2011, ISB named an award to encourage young people to stay involved in biomechanics research the "David Winter Young Investigator Award." Winter is notable for introducing many important methods and concepts to the study of human locomotion and balance, such as automated television motion capture, lowpass digital filtering of marker trajectories, measurement of instantaneous segmental energy, and the powers produced by joint moments of force, and the analysis of electromyograms by ensemble averaging.
