Recognition Taking a pragmatic and purposeful approach to life, Marjory Stephenson had little time for pride or egotism in others. Joan Mason relays the aside that she used to make fun of her male colleagues ‘fussing about their reputations... as if they were aging virgins in a Victorian novel’.1 In publication, she would take credit where credit was due – her name appeared only when she felt she had contributed sufficiently to the final outcome.2 Nevertheless, Stephenson herself was recognised for her achievements in the form of scholarships, awards, memberships, appointments and honorary degrees. Having obtained an MBE in recognition of her humanitarian war-work (December 1918), Stephenson waited many more years for similar recognition within the scientific community. For many years during the 1920s, Stephenson existed on annually-renewed Medical Research Council (MRC) grants. In 1929, the MRC recruited Stephenson to its external staff and in 1936 Cambridge awarded her an ScD degree for outstanding research.3 Even so, it was not until 1943 that Cambridge finally appointed Stephenson to a university lectureship, at the age of 58. Perhaps most significant to the history of women in science was Stephenson’s Fellowship of the Royal Society (FRS). In a further reflection of Stephenson’s aversion to the rituals of status, she chose to leave the country to avoid further publicity when her nomination was announced.4 It was then awarded to Stephenson in 1945, who became the first woman FRS (alongside that of Kathleen Lonsdale). -
3. Hopkins's Protégé
Early Women Biochemists >> Marjory Stephenson 3 Frederick Gowland Hopkins, c. 1943. Cambridge University Archives, Biochemistry Department Photograph Albums. Hopkins’s protégé A characterful portrait of Frederick Gowland Hopkins (1861-1947), taken towards the end of his life in c. 1943. It was Hopkins who mentored Stephenson at a critical period in her career after 1919. From 1919, Stephenson worked on vitamins and nutrition with Hopkins at Cambridge. It was on his advice that she switched to bacterial metabolism. According to the historian Robert Kohler, this fitted with Hopkins’s grand schema for ‘general biochemistry’ and provided a ready-made niche for Stephenson to ‘push beyond the limits of the biochemical tradition’. Equally, Kohler has also suggests that ‘the substance that Stephenson gave to the new field... was distinctly her own’.1 The acknowledgements to Stephenson’s Bacterial Metabolism (1930) recorded her debt of gratitude to Hopkins, at whose suggestion, she claimed, ‘the book was written and to whose influence alone I owe the incentive to think on biochemical matters’.2 Stephenson’s biographers, however, have also noted that she was an energetic independent investigator, who according to Robertson ‘took her fair share in the hard work of the subject’.3 By the 1940s, any deference Stephenson felt for Hopkins appears to have transmuted into a mutual respect. Her obituarist, D.D. Woods noted in 1950 that whilst her admiration for ‘Hoppy’ remained undiminished, she had become a ‘great standby to Hopkins in the running of his department, in which she had by then become a leading personality’.4 1 Robert Kohler, ‘Innovation in Normal Science: Bacterial Physiology’, Isis 76 (1985), pp. -
Joseph Needham-A Publication History
Chinese Science 14 (1997): 90--132 Joseph Needham-A Publication History Gregory Blue AUTHOR'S NOTE: I am grateful to Catherine Jami, Georges Metailie, John Moffett, and Nathan Sivin for help in sorting out a number of questions relating to the publication record, to Francesca Bray for discussing the general task at hand, and to Richard Gunde for his attention in preparing the text for press. {Gregory Blue teaches world history at the University of Victoria in Victoria, British Columbia, and is currently working on an intellectual biography of Joseph Needham. From 1977 to 1990 he was a Research Associate at the East Asian History of Science Library I Needham Research Institute in Cambridge, England.} * * * Introduction ambridge dons, like those elsewhere, come with various types of Cpublication profile. Both Wittgenstein and Sraffa changed the direction of intellectual endeavour in their disciplines twice, each time with a single powerful volume, but they published little else. At the other end of the spectrum, Bertrand Russell came close to realising his youthful ambition of publishing a book a year. Joseph Needham, their younger contemporary who devoted his later decades to promoting the history of Chinese science as a field of scholarship, must clearly be placed at the prolific end of the spectrum. As with Russell, his varied publication record reflects the many facets of the author's personality and his diverse talents and interests. The annotated list of Needham's works below is meant as a guide to his lengthy and somewhat labyrinthine publication trail. For reasons of space, purely scientific articles related to biochemistry, experimental embryology, and experimental morphology have been omitted (a list of these was given by Lu Gwei-Djen in the 1982 Shanghai Festschrift). -
A Quaker Upbringing

Brownlee Excerpt More information 1 A Quaker upbringing Biography is perhaps one of the most difficult of all historical and literary ventures, because it involves not only the compilation of material and its understanding, but also an attempt, which can never be wholly satisfactory, to enter into the soul of the subject and to create an honest account of life 1 as well as to present a portrait. icely Crewdson, an elegant lady in her late thirties, was on holiday Cwith her father at their family holiday home in the small village of Syde in the Cotswolds. Her holiday was nearly spoiled because she needed urgent treatment for a septic finger. Sepsis was potentially life- threatening in those days before effective antibiotics, such as penicillin, were available. The local doctor was summoned and agreed to come over from the nearby village of Rendcomb to treat Cicely. The doctor’s name was Frederick Sanger and he was still a bachelor. Her treatment would have needed a number of visits by this doctor to see how the patient’s finger was improving. Cicely Crewdson and Frederick Sanger got to know one another and doctor and patient were married in 1916. We can only guess what attracted Frederick and Cicely to one another but Frederick would have been a quite suitable match for Cicely. Edu- cated at St John’s College, Cambridge, he qualified as a doctor and completed his MD in 1902. Soon after he travelled to China as a missionary where he worked as a hospital doctor and found time, energy 1 © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-107-08334-9 - Fred Sanger Double Nobel Laureate: A Biography George G. -
Marjory Stephenson Obituary Notice
*No*2, Volume 3 of the Journal of General Microbiology was issued on 24 June 1949 Obituary Notice MARJORY STEPHENSON, 1885-1948 The death of Marjory Stephenson on 12 December 1948 has robbed bio- chemistry of a vigorous and productive exponent, and microbiology of a valuable interpreter of the chemical way of thinking. She was born on 24 January 1885 at Burwell, twelve miles from Cambridge; her life centred on Cambridge; she knew the town well and was well known in it. After graduating from Newnham she had hoped to complete a medical course but found it necessary to study Domestic Science at the Gloucestershire Training College instead, and she taught for a time there and at King’s College of Household Science, London. Her career as a biochemist started at University College, London, working with R. H. A. Plimmer. In later life she always spoke of him with gratitude for providing her with this opportunity. She there studied the lactase of intestinal mucosa and showed that this enzyme was inhibited by glucose but not by galactose (Stephenson, 1911). She turned next to the synthesis of esters of palmitic acid (Stephenson, 1913) and then worked on metabolism in experimental diabetes (Moorhouse, Paterson & Stephenson, 1915). This work was interrupted by the 1914-18 war, during which she served with the Red Cross in France and at Salonika. After the war she returned to Cambridge and worked in the department of Frederick Gowland Hopkins on the fat-soluble vitamins (Stephenson & Clark, 1920; Stephenson, 1920). Hopkins in his wisdom encouraged her to leave the fields of animal metabolism and vitamins and to initiate a comprehensive study of the biochemical activities of bacteria. -
Chemical Microbiology, an Interdisciplinary Field on the Road to Molecular Biology, 1920-1948
Chemical Microbiology, an Interdisciplinary Field on the Road to Molecular Biology, 1920-1948 Sonˇ a Sˇ trbánˇová* Since the second half of the 19th century scientific development has been charac- terised among others by intense integration and differentiation of scientific disci- plines resulting in the evolvement of new interdisciplinary sciences and fields. This is also true about chemistry which has interacted with numerous other dis- ciplines and fields with serious consequences for the structure of scientific disci- plines which was this way enriched with new interdisciplinary fields and sciences. Although a number of authors attempted to characterise and analyse the notions of “scientific discipline”, “interdisciplinary science” or “interdisciplinary field”,1 historians of science still have not agreed on their generally acceptable defini- tions. This paper is aimed at contributing to this discussion using the example of emergence of chemical microbiology which became constituted between 1930 and 1950, approximately, on the boundary of several chemical and biological disciplines. From biochemistry to chemical microbiology In order to understand the genesis of chemical microbiology it is necessary to recall a few particulars related to the formation of biochemistry, one of its “par- ent” interdisciplinary sciences, which dominated the scientific scene in the first half of the 20th century.2 As many historians have agreed, biochemistry became an independent discipline after 1900 with all necessary attributes: an institutional and communication base, an international scientific community, an independent subject taught in a number of universities, with a specific social mission and social acknowledgement and various strategic concepts outlining its program.

Sir Fredrick Gowland Hopkins: the Father of Biochemistry
Sir Fredrick Gowland Hopkins: The Father of Biochemistry 28 November 2013 | Column | By Hiteshi Dhami-Shah Sir Hopkins best remembered for his discovery of ‘vitamins’ has contributed immensely to the field of biochemistry, which was initiated as physiological chemistry on the continent. It is difficult to discuss in detail all the significant discoveries made by him in this article. Some of the most important discoveries, which shaped the field of biochemistry, are highlighted by Hiteshi Dhami-Shah, a Clinical Nutritionist and Research Fellow at Kasturba Health Society – Medical Research Centre, Mumbai, in this article. The discovery and establishment of dynamic biochemistry as a subject can be credited to Sir Frederick Gowland Hopkins. Popularly known as the ‘father of biochemistry’, Hopkins is best remembered for his discovery of ‘vitamins’, with Christiaan Eijkman, for which they were jointly, awarded the Nobel Prize for Physiology or Medicine in 1929. In addition to the Nobel Prize, Hopkins was conferred with numerous awards like the Royal Medal and the Copley Medal of the Royal Society, Fellowship of the Royal Society, knighthood by King George V and the award of the Order of Merit. Inspite of having such an illustrious career, his life has enough struggles. Probably, the early hardship in life prepared him to earn laurels in later life, with grace and dignity. Frederick Gowland Hopkins was born in Eastbourne, England on June 20, 1861. Ever Sir Fredrick Gowland Hopkins since early childhood his inclination towards science was evident. This can be observed from his childhood tryst with his father’s microscope. He later wrote for the microscope that; ‘It was the most important thing I had yet come up against; so much more significant than anything I was being taught at school’. -
