{{short description|British theoretical chemist (1925–2004)}}
Sir '''John Anthony Pople''' ([[October 31]], [[1925]] - [[March 15]],[[2004]]) was a [[theoretical chemistry|theoretical chemist]]. Born in [[England]], he attended [[Bristol]] Grammar School, where an [[Information technology|IT]] room is named after him. He came to the [[United States of America]] in the 1950s, where he lived the rest of his life, though he retained British citizenship. He received his B. A. (in 1946) and [[doctorate]] (in [[1951]]) [[degree]]s in [[mathematics]], from [[Cambridge University]] in the [[United Kingdom]]. His thesis was, however, on a topic that would generally be considered [[chemistry]]: the bonding structures of [[water]]. Pople considered himself more of a mathematician than a chemist, but theoretical chemists consider him one of the most important of their number.

His first major contribution was a theory of approximate [[molecular orbital]] (MO) calculations on [[pi electron]] systems in [[1953]], identical to the one developed by [[Rudolph Pariser]] and [[Robert G. Parr]] in the same year, and now called the [http://www.quantum-chemistry-history.com/Popl_Dat/Pople2.htm Pariser-Parr-Pople] (PPP) method. Subsequently, he developed the methods of [[Complete Neglect of Differential Overlap]] (CNDO) (in [[1965]]) and [[Intermediate Neglect of Differential Overlap]] (INDO) (shortly later) for approximate MO calculations on three-dimensional molecules, and other developments in [[computational chemistry]]. He pioneered the development of more sophisticated computational methods, so called [[ab initio]] methods, that used basis sets of either [[Slater type orbital]]s or [[Gaussian orbital]]s to model the wave function. While in the early days these calculations were extremely expensive to perform, the advent of high speed microprocessors has made them much more feasible today. He was instrumental in the development of one of the most widely used computational chemistry packages, the "Gaussian(tm)" suite of programs. However, since 1991, Pople was excluded from development of the software. In fact, he was actually [[banned by Gaussian]] from even using their software.


==Early life and education==
In [[1986]] he moved from [[Carnegie-Mellon University]] in [[Pittsburgh, Pennsylvania]], where his earlier accomplishments were made, to [[Northwestern University]] in [[Chicago, Illinois]].
Pople was born in [[Burnham-on-Sea]], Somerset, and attended the [[Bristol Grammar School]]. He won a scholarship to [[Trinity College, Cambridge]], in 1943. He received his Bachelor of Arts degree in 1946. Between 1945 and 1947 he worked at the [[Bristol Aeroplane Company]]. He then returned to the [[University of Cambridge]] and was awarded his PhD in [[mathematics]] in 1951 on [[lone pair]] [[electron]]s.<ref name=mathgene/>


==Career==
He received the [[Nobel Prize in Chemistry]] in [[1998]]. He was knighted in [[2003]].
After obtaining his PhD, he was a research fellow at [[Trinity College, Cambridge]] and then from 1954 a lecturer in the [[Faculty of Mathematics, University of Cambridge|mathematics faculty at Cambridge]]. In 1958, he moved to the [[National Physical Laboratory, UK|National Physical Laboratory]], near London as head of the new basics physics division.

Sir John Anthony Pople KBE FRS[1] (31 October 1925 – 15 March 2004)[1][6] was a British theoretical chemist who was awarded the Nobel Prize in Chemistry with Walter Kohn in 1998 for his development of computational methods in quantum chemistry. [7][8][9][10][11]

Early life and education

[edit]

Pople was born in Burnham-on-Sea, Somerset, and attended the Bristol Grammar School. He won a scholarship to Trinity College, Cambridge, in 1943. He received his Bachelor of Arts degree in 1946. Between 1945 and 1947 he worked at the Bristol Aeroplane Company. He then returned to the University of Cambridge and was awarded his PhD in mathematics in 1951 on lone pair electrons.[2]

Career

[edit]

After obtaining his PhD, he was a research fellow at Trinity College, Cambridge and then from 1954 a lecturer in the mathematics faculty at Cambridge. In 1958, he moved to the National Physical Laboratory, near London as head of the new basics physics division. He moved to the United States of America in 1964, where he lived the rest of his life, though he retained British citizenship. Pople considered himself more of a mathematician than a chemist, but theoretical chemists consider him one of the most important of their number.[12] In 1964 he moved to Carnegie Mellon University in Pittsburgh, Pennsylvania, where he had experienced a sabbatical in 1961 to 1962. In 1993 he moved to Northwestern University in Evanston, Illinois, where he was Trustees Professor of Chemistry until his death.[13]

Research

[edit]

Pople's major scientific contributions were in four different areas:[14]

Statistical mechanics of water

[edit]

Pople's early paper on the statistical mechanics of water, according to Michael J. Frisch, "remained the standard for many years".[14][15] This was his thesis topic for his PhD at Cambridge supervised by John Lennard-Jones.[2][12]

Nuclear magnetic resonance

[edit]

In the early days of nuclear magnetic resonance he studied the underlying theory, and in 1959 he co-authored the textbook High Resolution Nuclear Magnetic Resonance with W.G. Schneider and H.J. Bernstein.[14]

Semi-empirical theory

[edit]

He made major contributions to the theory of approximate molecular orbital (MO) calculations, starting with one identical to the one developed by Rudolph Pariser and Robert G. Parr on pi electron systems, and now called the Pariser–Parr–Pople method.[16] Subsequently, he developed the methods of Complete Neglect of Differential Overlap (CNDO) (in 1965) and Intermediate Neglect of Differential Overlap (INDO) for approximate MO calculations on three-dimensional molecules, and other developments in computational chemistry. In 1970 he and David Beveridge coauthored the book Approximate Molecular Orbital Theory describing these methods.

Ab initio electronic structure theory

[edit]

Pople pioneered the development of more sophisticated computational methods, called ab initio quantum chemistry methods, that use basis sets of either Slater type orbitals or Gaussian orbitals to model the wave function. While in the early days these calculations were extremely expensive to perform, the advent of high speed microprocessors has made them much more feasible today. He was instrumental in the development of one of the most widely used computational chemistry packages, the Gaussian suite of programs, including coauthorship of the first version, Gaussian 70.[17] One of his most important original contributions is the concept of a model chemistry whereby a method is rigorously evaluated across a range of molecules.[14][18] His research group developed the quantum chemistry composite methods such as Gaussian-1 (G1) and Gaussian-2 (G2). In 1991, Pople stopped working on Gaussian and several years later he developed (with others) the Q-Chem computational chemistry program.[19] Prof. Pople's departure from Gaussian, along with the subsequent banning of many prominent scientists, including himself, from using the software gave rise to considerable controversy among the quantum chemistry community.[20]

The Gaussian molecular orbital methods were described in the 1986 book Ab initio molecular orbital theory by Warren Hehre, Leo Radom, Paul v.R. Schleyer and Pople.[21]

Awards and honours

[edit]

Pople received the Nobel Prize in Chemistry in 1998.[22] He was elected a Fellow of the Royal Society (FRS) in 1961.[1] He was made a Knight Commander (KBE) of the Order of the British Empire in 2003. He was a founding member of the International Academy of Quantum Molecular Science.

An IT room and a scholarship are named after him at Bristol Grammar School, as is a supercomputer at the Pittsburgh Supercomputing Center.

Personal life

[edit]

Pople married Joy Bowers in 1952 and was married until her death from cancer in 2002. Pople died of liver cancer in Chicago in 2004. He was survived by his daughter Hilary, and sons Adrian, Mark and Andrew.[23] In accordance with his wishes, Pople's Nobel Medal was given to Carnegie Mellon University by his family on 5 October 2009.
