Fracture Mechanics (the study of cracks in structural materials) was pioneered by Griffith and was well known prior to WWII. He's not exactly "obscure" in the field of mechanical/aerospace engineering. EDIT: Although, I do remember hearing my material science professer tell us that it was not actually Griffith who came up with the theory, but one of his graduate students. Anyone know more about the history here?
