We are grateful to Chris Hawkesworth and Simon Turner for their general comments on the manuscript and to Mary Reid and Georg Zellmer for their thoughtful and constmctive reviews, which helped to improve the first version of this chapter. 

Overlapping with Browne, Mary Christina Thompson41 was appointed in 1938 as Demonstrator and Assistant Lecturer. Mary, the daughter of William Thompson, a London accounts clerk, was educated at James Allen s Girls School, Dulwich. She entered Bedford College in 1930, completing her B.Sc. in 1933, then continued to a Ph.D. in organic chemistry with Eustace Turner.42... 

Mole then undertook research towards a Ph.D. with Eustice Turner at Bedford, which she was awarded in 1938. She continued research with Turner for another year, investigating molecular dissymmetry due to restricted rotation in diphenylamines and triphenylamines, before obtaining an appointment with ICI, first at Widnes, then in the Technical Services Department in Liverpool. One of her nominators in 1941 for admission as Fellow of the Chemical Society was ICI Librarian, Mary Eynon Miller (see above).

In support of Mary Lyon s hypothesis is the fact that the number of chromatin bodies found in individuals is equal to the number of X chromosomes in the karyotype minus one. However, the second X chromosome cannot be considered to be totally unnecessary. If it were, the XO karyotype would not lead to the clinical symptomatology found in Turner s syndrome, nor would an XXY karyotype result in a phenotype different from XY. It has been proposed that the second X chromosome might affect the expression of the genotype in the phenotype simply by its presence. The number of ridges in the fingerprint decreases as the number of genetically inactive X chromosome increases. The Y chromosome unquestionably determines the male sex characteristics, and the male sex characteristics develop in the phenotype even if the karyotypes contain as many as three X chromosomes. Whether the Y chromosome determines the appearance of the phenotype because it stores specific genes or simply because of its presence in the karyotype has not been established.
