Marguerite Henry, Australian zoologist (died 1982)

Marguerite Henry was an Australian zoologist known for her research on freshwater crustaceans; she was active in the early 20th century. Henry's work contributed to the taxonomy and ecology of Australia's freshwater entomostracans, describing dozens of new species and establishing a new genus of copepods, Gladioferens. Her research, supported by the Australian government and the Linnean Society of New South Wales, focused on cladocerans, copepods, ostracodes, and phyllopods, with her findings published in a series of detailed monographs between 1919 and 1924.
