It is with great sadness that we inform the International Biomechanics community of the passing of Professor David Winter. David Winter had a pioneering role in defining the biomechanics field. His methods and rationale for using biomechanics to understand movement are foundational to the modern science of biomechanics. The International Biomechanics community passes our sincere condolences to David's family. Details about David, visitation and funeral arrangements can be found at this link.
