May 4, 1902

Sidnie Manton (May 4, 1902 to January 2, 1979) appears not to have used her married name, Harding, professionally. She is the author of Colourpoint, Himalayan and Longhair Cats (1971), which drew upon her expertise and research in genetics. She is in fact better known as the scholar whose research in arthropods led to a life in academe; for decades she was associated with Kings College, London. The publication of The Arthropoda: Habits, Functional Morphology and Evolution, in 1977, reflected a life of research. According to her Dictionary of National Biography article her honors included

... election as a fellow of the Royal Society in 1948. Her sister, Irene Manton, professor of botany at Leeds University, later also achieved this distinction, the only case involving two sisters in the history of the society. She was awarded the gold medal for zoology of the Linnean Society (1963) and the Frink medal of the Zoological Society (1977), as well as an honorary doctorate of the University of Lund, Sweden.

This human glimpse is from the same source:

Spare of frame and always interested in sport, Sidnie Manton was the Cambridge swimming captain in 1923 and a hockey blue in 1924; she played tennis until well into her sixties.

Her husband, whom she married in 1937, Philip Harding (1911 to 1998), would become keeper of zoology at the British Museum. So one may assume it was a marriage also of minds.
