Aaron Klug

Template:Short description Template:Use dmy dates Template:Infobox scientist Sir Aaron Klug (11 August 1926 – 20 November 2018) was a British biophysicist and chemist. He was a winner of the 1982 Nobel Prize in Chemistry for his development of crystallographic electron microscopy and his structural elucidation of biologically important nucleic acid-protein complexes.

Klug was born in Želva, in Lithuania, to Jewish parents Lazar, a cattleman, and Bella (née Silin) Klug, with whom he emigrated to South Africa at the age of two. He was educated at Durban High School. Paul de Kruif's 1926 book, Microbe Hunters, aroused his interest in microbiology.<ref name="Guardian1"/>

Klug was part of the Hashomer Hatzair Jewish Zionist youth movement in South Africa.<ref>Template:Cite book</ref>Template:Page needed Template:Better source needed

He started to study microbiology, but then moved into physics and maths, graduating with a Bachelor of Science degree at the University of the Witwatersrand, in Johannesburg. He studied physics under Reginald W. James and obtained his Master of Science degree at the University of Cape Town.<ref name=whoswho>Template:Who's Who</ref> He was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851,<ref name="Guardian1"/> which enabled him to move to England, completing his PhD in research physics at Trinity College, Cambridge in 1953.<ref name=aphd>Template:Cite thesis</ref>

Career and researchEdit

Following his PhD, Klug moved to Birkbeck College in the University of London in late 1953, and started working with chemist and X-ray crystallographer Rosalind Franklin in the lab of crystallographer John Bernal. This experience aroused a lifelong interest in the study of viruses, and during his time there he made discoveries in the structure<ref>Template:Cite journal</ref> of the tobacco mosaic virus. In 1962 he moved to the newly built Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) in Cambridge. Over the following decade Klug used methods from X-ray diffraction, microscopy and structural modelling to develop crystallographic electron microscopy in which a sequence of two-dimensional images of crystals taken from different angles are combined to produce three-dimensional images of the target. He studied the structure of transfer RNA, and found what is known as zinc fingers as well as the neurofibrils in Alzheimer's disease.<ref name=lance>Template:Cite journal</ref>

Also in 1962, Klug became a Fellow of Peterhouse, Cambridge. He was later made an Honorary Fellow of the college.<ref name=whoswho/>

Between 1986 and 1996, Klug was director of the LMB.

Awards and honoursEdit

Klug was awarded the Louisa Gross Horwitz Prize from Columbia University in 1981. He was knighted by Elizabeth II in 1988.<ref name=virt>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 1969 he was elected a Fellow of the Royal Society (FRS),<ref name=frs>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> the oldest national scientific institution in the world. He was elected its President (PRS) from 1995 to 2000. He was appointed to the Order of Merit in 1995 – as is customary for Presidents of the Royal Society.

Klug was a member of the American Academy of Arts and Sciences<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and the American Philosophical Society<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 2000, Klug received the Golden Plate Award of the American Academy of Achievement.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2005, he was awarded South Africa's Order of Mapungubwe (gold) for exceptional achievements in medical science.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> He was elected a Fellow of the Academy of Medical Sciences (FMedSci), also in 2005.<ref name="fmedsci">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 2013, Israel's Ben-Gurion University of the Negev dedicated their centre for structural biology in Klug's name, Aaron Klug Integrated Centre for Biomolecular Structure. He, his family and the then-British Ambassador to Israel Matthew Gould, were in attendance. Klug was associated with the university and the town of Be'er Sheva, having visited them numerous times.<ref name="BGU1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Guardian1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Personal lifeEdit

Klug married Liebe Bobrow in 1948;<ref name=whoswho/> they had two sons, one of whom predeceased them in 2000.<ref name="Guardian1"/> He died on 20 November 2018 in Cambridge.<ref>Template:Cite journal</ref>

Though Klug had faced discrimination in South Africa, he remained religious and according to Sydney Brenner, he became more religious in his older age.<ref>Hargittai, Istva'n & Magdolna. 2006. Candid Science VI: More Conversations with Famous Scientists. Imperial College Press, p. 33</ref>
