Lloyd, Dorothy Jordan

The biochemist Dorothy Jordan Lloyd, researcher with F. Gowland Hopkins at Cambridge (see Chap. 8), was also given a specific task. On the outbreak of war, the Medical Research Committee assigned her to study culture media for meningococcus, one of the anaerobic pathogens involved in trench diseases, and the causes and prevention of ropiness in bread.43 Jordan Lloyd was one of several women with a background in biochemistry who were enlisted in the war effort.

Smedley was not the only one to be chosen as the expectation for a woman chemist or biochemist. A 1929 article in the Journal of Careers18 held up Martha Whiteley (Chap. 3) as a role model while an article in the same journal in 193819 extolled Ida Smedley (Chap. 2), Marjory Stephenson (Chap. 8), Katherine Coward (see below), and particularly Dorothy Jordan Lloyd (Chap. 8) as the heights of careers to which women chemists and biochemists could aspire — but only those who were exceptional. 

In her article titled Biochemistry as a Career for Women in the Journal of Careers, Dorothy Jordan Lloyd made it clear that the biochemical sciences were among the most demanding in preparation ...

Thomas Graham used the term gel in 1861 for the first time, and nowadays it is a common household item which is easily identified by the simple inversion test if the material is able to support its own weight without falling out when a pot is turned upside down, it is considered as a gel [6, 7]. However, as Dorothy Jordan Lloyd noted in 1926, gels are. . easier to recognize than to define. The generally accepted definition is that given by Flory in 1974, which is the next A gel is a two-component, colloidal dispersion with a continuous structure with macroscopic...
