Karl Pearson is a figure of interest to historians of many areas. The historian of mathematical statistics knows the inventor of the product-moment correlation coefficient and the chi square test; the historian of philosophy knows the author of the Grammar of science; the historian of genetics knows the opponent of Mendelism; the political historian knows the ‘social-imperialist’ political thinker; the historian of feminism knows the early supporter of the women's movement and friend of Olive Schreiner; and, of course, the historian (...) of eugenics knows the first occupant of the only chair of eugenics in a British university. This paper does not attempt a biography of Pearson, but simply raises and tries to answer one question. To what extent can the sociology of knowledge throw light on Pearson's varied and many-sided thought? It concludes that there is a good case for seeing this thought as reflecting with exceptional clarity the social interests of the professional middle class to which he belonged. (shrink)

Because Francis Galton (1822-1911) was a well-connected gentleman scientist with substantial private means, the importance of the role he played in the professionalization of the Victorian life-sciences has been considered anomalous. In contrast to the X-clubbers, he did not seem to have any personal need for the reforms his Darwinist colleagues were advocating. Nor for making common cause with individuals haling from social strata clearly inferior to his own. However, in this paper I argue that Galton quite realistically discerned in (...) the reforming endeavors of the 1860s, and beyond, the potential for considerably enhancing his own reputation and standing within both the scientific community and the broader Victorian culture. In addition, his professionalizing aspirations, and those of his reformist allies, were fully concordant with the interests, ambitions and perceived opportunities of his elite social group during the Victorian period. Professionalization appealed to gentlemen of Galton's status and financial security as much as it did to the likes of Thomas Huxley and John Tyndall, primarily because it promised to confer on the whole scientific enterprise an unprecedented level of social prestige.
