Sidnie Milana Manton FLS[1] FRS[2] (4 May 1902 – 2 January 1979) was an influential British zoologist.

[4] Sidnie Milana Manton was born in Kensington, London the daughter of a descendant of French aristocracy and a dentist.

[6] She came top of the class list, but was not awarded the prize that that position usually brings, because women were not at that time officially members of Cambridge University.

[7] The Zoological Society of London awarded her the Frink Medal in 1977 for "the advances made by her towards the understanding of arthropod evolution.".

[7] Together these awards demonstrate the very high esteem in which her work was held during her lifetime, but recognition has also continued after her death.
