Question: What did British biochemist that led  theoretical chemistry in  Department of Chemistry, University of Cambridge won nobel prize for 
Context: Frederick Sanger ( ; 13 August 1918 – 19 November 2013) was a British biochemist who twice won the Nobel Prize in Chemistry, one of only two people to have done so in the same category (the other is John Bardeen in physics), the fourth person overall with , and the third person overall with two Nobel Prizes in the sciences.  In 1958, he was awarded a Nobel Prize in chemistry "for his work on the structure of proteins, especially that of insulin".  In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids".  The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant DNA". Lars Onsager (November 27, 1903 – October 5, 1976) was a Norwegian-born American physical chemist and theoretical physicist.  He held the Gibbs Professorship of Theoretical Chemistry at Yale University.  He was awarded the Nobel Prize in Chemistry in 1968. Henk Buck (born Dordrecht, 1930) is an organic chemist.  He studied at the University of Leiden where he received his PhD in 1959.  He got a lectorship at the University in Theoretical Organic Chemistry in 1964.  For his research he received the Golden Medal of the Royal Netherlands Chemical Society in 1967.  In 1970 he was appointed as professor of Physical Organic Chemistry and Organic Chemistry at the University of Technology in Eindhoven.  Because there was no Chair for Theoretical Chemistry and Biochemistry he gave lectures in organic chemistry, physical organic chemistry, theoretical organic chemistry, biochemistry and biotechnology.  From 1988-1991 he was Dean of the Chemical Faculty.  For his scientific contributions he became a member of the Royal Netherlands Academy of Arts and Sciences in 1979.  During his scientific career he published more than 300 scientific papers spread over a large area of the chemical field.  Under his supervision 43 chemical engineers obtained their PhD.  The end of his career came prematurely because of a publication in Science in 1990 that had to be retracted because of flawed research. Eluvathingal Devassy Jemmis or E. D. Jemmis (born October 31, 1951) is a Professor of theoretical chemistry at the Indian Institute of Science, Bangalore, India.  He was the founding Director of Indian Institute of Science Education and Research, Thiruvananthapuram (IISER-TVM).  His primary area of research is applied theoretical chemistry with emphasis on structure, bonding and reactivity, across the periodic table of the elements.  Apart from many of his contributions to applied theoretical chemistry, an equivalent of the structural chemistry of carbon, as exemplified by the Huckel 4n+2 Rule, benzenoid aromatics and graphite, and tetrahedral carbon and diamond, is brought in the structural chemistry of boron by the Jemmis mno rules which relates polyhedral and macropolyhedral boranes to allotropes of boron and boron-rich solids.  He has been awarded Padma Shri in Science and Engineering category (year 2014) by the Government of India. Amyand "David" Buckingham, CBE, FRS, FAA (born 28 January 1930 in Pymble, Sydney, New South Wales, Australia) is a chemist, with primary expertise in chemical physics.  He is currently Emeritus Professor of Chemistry at the University of Cambridge, United Kingdom and Emeritus Fellow at Pembroke College, Cambridge.  He obtained a Bachelor of Science and Master of Science, under Professor Raymond Le Fevre, from the University of Sydney and a Ph.D. from the University of Cambridge supervised by John Pople.  He was an 1851 Exhibition Senior Student in the Physical Chemistry Laboratory at the University of Oxford from 1955–57, Lecturer and then Student (Fellow) at Christ Church, Oxford from 1955–65 and University Lecturer in the Inorganic Chemistry Laboratory from 1958 - 65.  He was Professor of Theoretical Chemistry at the University of Bristol from 1965 - 69.  He was appointed Professor of Chemistry at the University of Cambridge in 1969. The Department of Chemistry at the University of Cambridge is the chemistry department of the University of Cambridge.  It was formed from a merger in the early 1980s of two separate departments that had moved into the Lensfield Road building decades earlier: the Department of Physical Chemistry (originally led by Professor Ronald Norrish FRS, Nobel Laureate; the department was previously located near the Old Cavendish in Free Street - see photo) and the Department of Chemistry (that included theoretical chemistry and which was led by Lord Alexander R. Todd FRS, Nobel Laureate) respectively.  Research interests in the department cover a broad of chemistry ranging from molecular biology to geophysics.  The department is located on the Lensfield Road, next to the Panton Arms on the South side of Cambridge.  s of 2015 the department is home to around 200 postdoctoral research staff, over 250 postgraduate students, around sixty academic staff. The School of Chemistry is one of the 27 academic institutions that are part of the National Autonomous University of Mexico (UNAM).  The School carries out research activities in the fields of biochemistry, analytical chemistry, organic chemistry, physical chemistry, food chemistry, biotechnology, metallurgy, chemical engineering, pharmacy, inorganic chemistry, nuclear chemistry, theoretical chemistry and theoretical physics.  The School is organized into 12 scientific departments and 4 units. Theoretical Chemistry Accounts: Theory, Computation, and Modeling is a peer-reviewed scientific journal publishing original (primary) research and review articles in theoretical chemistry, quantum chemistry, and computational chemistry.  It was founded in 1962 as "Theoretica Chimica Acta".  The publisher is Springer Berlin Heidelberg.  The impact factor of this journal is 2.233 (2014).  The editor-in-chief is the team of Carlo Adamo and Ilaria Ciofini, the associate editor is Weitao Yang, and the chief advisory editor is Donald G. Truhlar. Alexander Robertus Todd, Baron Todd (2 October 1907 – 10 January 1997) was a British biochemist whose research on the structure and synthesis of nucleotides, nucleosides, and nucleotide coenzymes gained him the Nobel Prize for Chemistry. Gergely Tóth (born June 11, 1966, in Budapest, Hungary) is a theoretical chemist and university teacher of mathematical chemistry.  He graduated from Eötvös Loránd University, Faculty of Science, Department of Theoretical Chemistry and obtained his PhD in 1993 from the same institution.  From 1993–1995 he was a postdoctoral fellow at Max Planck Institute for Chemistry in Mainz, Germany.  From 1995–1997 he obtained Zoltán Magyary postdoctoral fellowship and from 1997–1999 Hungarian Scientific Research Fund postdoctoral fellowship at Eötvös Loránd University.  From 1999 he has a position at Institute of Chemistry, Eötvös Loránd University, Budapest.  In 2015–2017 he served as the vice-director of the institute.  He was a member of several local and national boards concerning chemistry education at secondary school and university levels.  He is the head of the EchemTest Center in Budapest and Member of the Label Committee of the European Chemistry Network Association.
