Sir Geoffrey I. Taylor
Taylor and Alan Arnold Griffith developed the use of soap films as a way of studying stress problems. One of the motivations was the need to determine the stresses in the aerofoil sections of airscrew blading. Griffith and Taylor presented an I MechE Paper on the subject in 1917, which gained the Thomas Hawksley Gold Medal. This method, and similar ones, were used well into the 1990s when computer power became generally available that could do the same experiment numerically.
