Geoffrey Ingram Taylor was born on 7 March 1886, the son of Edward Ingram Taylor and his wife Margaret, who was the daughter of the mathematician George Boole. He was admitted to Trinity College Cambridge in 1905 where he read first Mathematics and then Natural Sciences and was awarded first a Scholarship and then a Fellowship which he held from 1910 to his death, with a short gap during the First World War when he joined many other Trinity scientists at the RAF factory at Farnborough where he worked on problems in aerodynamics.
Before the war he had joined an expedition to observe the flow of icebergs in the wake of the Titanic disaster which led him to the study of turbulence, which he was able to pick up again on his return to Cambridge in 1919. Over the next 3 decades he produced a series of seminal articles which transformed understanding of the subject. In 1923 he was appointed Royal Society Yarrow research professor, a post he held until 1952. During the Second World War he spent some time working with the staff of the Los Alamos project. After his retirement from the chair he continued to research at the Cavendish Laboratory. He died in 1975.
Arthur Stanley Eddington was born in 1888 into a Quaker family, and remained of that religion all his life. He was educated at Brynmelyn School, Weston-super-Mare, and Owen’s College, Manchester, before coming up to Trinity College, Cambridge, in 1902. He graduated in 1905 and spent a short time in Cambridge as a mathematical coach, but in 1906 went to Greenwich as Chief Assistant to the Astronomer Royal. He returned to Cambridge in 1913 as Plumian Professor of Astronomy, and the following year was also appointed Director of the Cambridge Observatory. He held these posts for the rest of his life. Eddington’s most significant scientific contributions were to the study of the structure and movements of stars, the implications of Einstein’s theory of relativity, and the search for a ‘fundamental theory’ to unite the theories of relativity and quantum mechanics.
