An English astrophysicist, best known for his theories that galaxies contain massive black holes at their centre, and that such black holes are the principal source of energy in quasars. Lynden-Bell has been the president of the Royal Astronomical Society. He currently works at the Institute of Astronomy in Cambridge; he was the Institute's first director. Educated at the University of Cambridge, in 1962 he published research with Olin Eggen and Allan Sandage arguing that our galaxy originated through the dynamic collapse of a single large gas cloud. In 1969 he published his theory that quasars are powered by massive black holes accreting material. From counting dead quasars, he deduced that most massive galaxies have black holes at their centres.

Was an astronomer. Dorothea studied at the University of Paris and started out also studying music, but later turned to astronomy. She received her bachelor's degree in 1886 and took up a post at the Paris Observatory. Here she worked with Guillaume Bigourdan and Lipót Schulhof, and later with the pioneer astrophotographers Paul and Prosper Henry, who were working with a 34 cm refractor and photographing the minor planets (asteroids). Her work consisted of measuring star positions, processing astrophotographs, studying stellar spectra and meteorites.

Was a British chemist, credited with the discovery of protein crystallographyShe pioneered the technique of X-ray crystallography, a method used to determine the three dimensional structures of biomolecules. Among her most influential discoveries are the confirmation of the structure of penicillin that Ernst Boris Chain had previously surmised, and then the structure of vitamin B12, for which she was awarded the Nobel Prize in Chemistry. In 1969, after 35 years of work and five years after winning the Nobel Prize, Hodgkin was able to decipher the structure of insulin. X-ray crystallography became a widely used tool and was critical in later determining the structure of many biological molecules such as DNA where knowledge of structure is critical to a understanding of function.

An American economist known for his work in the history of economic thought. He the co-recipient (with Robert William Fogel) of the 1993 Nobel Memorial Prize in Economic Sciences. In the words of the Nobel Committee, North and Fogel were awarded the prize "for having renewed research in economic history by applying economic theory and quantitative methods in order to explain economic and institutional change."North was accepted at Harvard at the same time that his father became the head of MetLife on the west coast, so North opted to go to University of California, Berkeley. In 1942, North graduated with a B.A. in General Curriculum-Humanities. Although he his grades amounted to slightly better than a "C" average, North graduated with a triple major in political science, philosophy and economics.
