John A Pople

In 1952, Pople married Joy Bowers, his professional music teacher, whom he courted for long. The two remained together until her death in 2002. They were blessed with a daughter, Hilary and three sons, Adrian, ark and Andrew.

He died of liver cancer on March 15, 2004, in Chicago, at the age of 78.

To honour his contribution to the scientific world, an IT room in Bristol Grammar School and a scholarship at the institution have been named after him. Additionally, a supercomputer at the Pittsburgh Supercomputing Center bears his name.

John Anthony Pople was born on October 31, 1925 in Burnham-on-Sea, Somerset, England, to Keith Pople and Mary Jones. His father owned a men’s clothing store in Burnham.

After having attended a preparatory school in Burnham, Pople enrolled at the Bristol Grammar School in 1936. Two years later, when he was introduced to algebra, he drew a deep affinity for mathematics. In no time, he mastered the subject, way ahead of his school curriculum and started doing research projects on algebra. This early experiences instilled in young Pople the acumen required for research.

Pople’s proficiency at mathematics was soon discovered by his teachers and parents when he turned in a perfect paper for an unusually difficult test. Watching his talent, the school prepared him for a scholarship in mathematics at Cambridge University which he eventually won in 1943

From 1943, Pople attended Trinity College, Cambridge. He received his Bachelor of Arts degree in 1946. Meanwhile, from 1945 to 1947, he took up work at the Bristol Aeroplane Company.

Determined to use his mathematical skills in a branch of science, he decided to return to Cambridge and resume his studies. In 1947, he returned to Cambridge and began a career in mathematical science. He was awarded his PhD in mathematics in 1951 for his paper on statistical mechanics of water. This work which he had done under the supervision of John Lennard Jones remained the standard for many years.

After obtaining his Ph.D, John Pople served as a research fellow at Trinity College, Cambridge in 1951. Three years later, he was appointed as a lecturer in the mathematics faculty at Cambridge. He planned to develop mathematical models for stimulating a whole chemistry.

By the end of 1955, he developed an interest in nuclear magnetic resonance (NMR), which was emerging as a powerful technique for studying molecular structure. He spent the summers of 1956 and 1957 researching at the National Research Council in Ottawa, Canada, working on the theoretical background of NMR.

By 1958, Pople had turned from a mathematician to a practising scientist. Dissatisfied with his position at Cambridge, he moved to the National Physical Laboratory, where he took up the position of head of the new basics physics division. However, his stay at the National Physical Laboratory was short-lived as his position demanded too much administrative and institutional work which interfered with his research work.

While serving at the National Physics Laboratory, he spent a year in sabbatical at the Carnegie Mellon University in USA from 1961 to 1962. Impressed by the opportunities that the USA forwarded in chemical research, he resolved to move to United States permanently which he eventually did in 1964. Though Pople remained in USA for the rest of his life, he retained his British citizenship.

Meanwhile in 1959, he co-authored a textbook on ‘High Resolution Nuclear Magnetic Resonance’ with W.G. Schneider and H.J. Bernstein. The book underlined the theory of nuclear magnetic resonance.

Pople’s is best remembered as a pioneer in the field of quantum chemistry. He provided methods to calculate the bonding of atoms in molecules. His best bit came when he developed a computer program called Gaussian, which allowed the theoretical study of molecules, their properties and how they linked together in chemical reactions. Till date, Pople’s method is used by thousands of scientists in universities and industry around the world to study a vast range of problems in chemistry and biochemistry. With the aid of computer simulations, chemists can now predict how chemical substances will react with each other, in a way that is comparable to the methods used to solve elaborate mathematical equations to make weather forecasts, and calculate the structural integrity of bridges and the aerodynamic characteristics of aeroplanes.
