It is now possible to recognise aspects of their work not wholly visible to their contemporaries. This book was started with the intention of using the new opportunity to discuss some of these aspects. Inspiration was also derived from the instructive essay on The Social and Economic Roots of Newtons Principia communicated by Professor Hessen to the International Congress on the History of Science in 1931. Professor Hessen discussed in a manner not hitherto seen in English literature the relation between Newtons ideas and the social characteristics of his time. The first intention was to include about twenty scientists, but presently it became clear that the more remarkable could not be usefully discussed in short essays. It was also proposed to choose equal numbers of physical, bio logical, and medical scientists. A difficulty then arose. Investigation showed there were very few great British medical scientists in the nineteenth century, and that the number of great biologists was much smaller than the number of great physical scientists, of which Davy, Fara day, Joule, Thomson, and Maxwell appeared to be the most important. These have been chosen as the subjects. Dalton was excluded because he was already mature in the eighteenth century, and Rayleigh because he was too close to the twentieth. The rarity of important British medical scientists in the nineteenth century is noticeable. This may be due to the exclusiveness of the medical profession. They considered medicine an art distinct from science, and conducted their educational colleges apart from the universities. The theory of medicine was taught perfunctorily and the student hurried on to the empirical training in the hos pital. This utilitarian attitude was connected with the nature of the organisation of medical service. The private hospitals and doctors reflected the narrow views, common though not universal, in private institutions. In addition, the sciences of biology, chemistry, and physics were not developed enough to provide easy methods of investigating the complexities of human physiology.
