18. Early Life/Childhood Born on October 31, 1925 in the Burnham-on- Sea, Somerset, England

19. Early Life/Childhood Father, Keith Pople  owned a clothing shop Mother, Mary Jones  served as a tutor to the area's wealthy families  also worked as an Army librarian during World War I

20. Early Life/Childhood At age 12  developed an intense interest in mathematics  He rescued a calculus book from the trash and read it cover to cover At age 13  started some research projects on formulating the theory of permutations

21. Education Attended Bristol Grammar School  30 miles away from Pople’s home

22. Education During World War II  shipping port of Bristol was frequently bombed by enemy raid  classes were held in deep underground bunkers.

23. Education  1943  earn a math scholarship to Cambridge University's Trinity College  first member of his family to attend college

24. Education  1945  earned his mathematics degree Took a job with the Bristol Aeroplane Company  1951  earned his doctoral degree in mathematics in 1951

25. Scientific Career  1958  worked as a research fellow and mathematics lecturer at Cambridge  head of the physics division of England's National Physical Laboratory

26. Scientific Career  1964  teaching chemical physics at Pittsburgh's Carnegie Institute of Technology (Carnegie-Mellon University)

27. Scientific Career  Pople concentrated his efforts on exploring the electronic structure of molecules  Research culminated in a computer program called Gaussian-70

28. Major Scientific Contributions Statistical mechanics of water Nuclear magnetic resonance Semi-empirical theory  MO Theory  Developed methods of Complete Neglect of Differential Overlap (CNDO) and Intermediate Neglect of Differential Overlap (INDO) for approximate MO calculations on three-dimensional moleculesCNDOINDO

29. Major Scientific Contributions Ab initio electronic structure theory  Ab initio quantum chemistry methods  Gaussian computer program -widely used used in chemical research from pharmaceuticals to plastics  Founder of the Q-Chem computational chemistry program.

32. Scientific Awards and Honors  1998  received the Nobel Prize in Chemistry along with Walter Kohn for work on computational methodology in quantum chemistry  2003  Knight Commander (KBE) of the Order of the British EmpireOrder of the British Empire

33. Love Life/Family Life Took up the piano lesson  hired Joy Bowers to instruct him  1952  Pople and Joy married Has one daughter, Hilary and three sons Adrian, Mark, and Andrew Has eleven grandchildren, and a great- granddaughter

34. Death  2002  Wife died of cancer  March 15,2004  Pople died of liver cancer

35. “I must emphasize that my contribution to quantum chemistry has depended hugely on work by others.” “The international community in our field is a close one, meeting frequently and exchanging ideas freely.” “I am delighted to have had students, friends and colleagues in so many nations and to have learned so much of what I know from them. “ “This Nobel Award honours them all.”
