Prof L. M. Brown B.A.Sc. (Tor), Ph.D. (B’ham), M.A., Sc. D. (Cantab), F. Inst. P., F. I. M., Hon. F. R.M.S., F.R.S. is a Canadian by birth whose career has been almost entirely in England.  He is now a Founding Fellow of Robinson College and a Professor Emeritus at the Cavendish Laboratory.  He has published many papers in solid state physics and electron microscopy, particularly on work-hardening and fatigue of metals.  Using electron energy loss spectrometry he and his students established the platelet structure of nitrogen contained in diamond.  More recently, with Ondrej Krivanek he pioneered the design and installation of a practical corrector for spherical aberration in scanning transmission electron microscopes, leading to the establishment of the SuperSTEM facility in Daresbury, Cheshire.  Most of these papers were first published in EMAG conference proceedings over the years.  He has acted as Chair and Editor of EMAG, as well as an enthusiastic supporter of it.   His most recent work has been to elucidate the mechanisms of crack initiation and the nature of the fatigue limit in ductile metals; also to model uniaxial deformation in the light of self-organised criticality, thereby deriving the various observed power laws relating mechanical properties.
