The following is an edited version of the Von Hippel Award address, given by recipient Sir Alan Cottrell at the 1996 MRS Fall Meeting. Cottrell received the Materials Research Society's highest honor for “converting crystal dislocations from a hand-waving hypothesis to a rigorous discipline, transforming the understanding of brittle fracture, making varied and crucial advances in the theory of radiation damage, and for transforming the teaching of materials science throughout the academic world through his pioneering textbooks.” Cottrell is an honorable distinguished research Fellow in the Department of Materials Science and Metallurgy, University of Cambridge.
