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. -

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.
