Marjorie Katharine Mestayer

Marjorie Katherine Mestayer (1880 – 7 September 1955) was a New Zealand curator and conchologist. She is best known for the molluscan, foraminiferal and ostracod species named after her. Beginning as an amateur shell enthusiast, she went on to work as a conchology curator for the Dominion Museum in Wellington. She also received grants for her conchology research. She donated scientific and personal collections to the Museum of New Zealand Te Papa Tongarewa.

History In 1880, Mestayer was born in England. Her family migrated to Australia when she was 2, and to Wellington when she was 12. Her father, Richart Mestayer, was "an amateur naturalist with interests in things microscopic, like foraminifera. Undoubtedly his enthusiasm for the natural world rubbed off on Marjorie". She also donated specimens to the Auckland Museum, where her frequent correspondent, Baden Powell, was the chief conchologist. Her works included 18 publications between 1907 and 1930. She focused on gastropods and chitons. Much of her work turned out to be synonyms or replication, due to issues in obtaining current literature. Much of her work is still considered to be valid. She was also the subject of a popular culture profile in the newspaper NZ Truth: Mestayer died in 1955. In 2017, Mestayer was selected as one of the Royal Society Te Apārangi's "150 women in 150 words", a project celebrating the contributions of women to expanding knowledge in New Zealand.
