A Nobel laureate in Chemistry, Aaron Klug needs no introduction of any kind. He is the man behind the development of crystallographic electron microscopy. His technique of restructuring two dimensional image to three dimensional one has been applied in various arenas, the most prominent one being the CT scan. Born in Zel'va, BiaÅ‚ystok Voivodeship, to Jewish parents, he moved to South Africa with his family when he was two. Interested in science from a young age, he went on to graduate with a Bachelor of Science degree from the University of the Witwatersrand before completing his Master of Science degree at the University of Cape Town. Eventually he moved to England and earned his PhD at Trinity College, Cambridge. He began working with Rosalind Franklin in John Bernal's lab at the Birkbeck College in the University of London. This kindled in him a lifelong interest in viruses. Klug went on to study helical viruses to reveal how protein units are formed, investigated the polio virus with J. D. Bernal, and researched the structure and action of transfer DNA (deoxyribonucleic acid). A much renowned chemist, he received several prestigious awards for his development of crystallographic electron microscopy and his structural elucidation of biologically important nucleic acid-protein complexes.
