On November 5, 1900, one of the 20th century’s most beloved and honored ichthyologists was born in Penzance, Cornwall, England -- Ethelwynn Trewavas, affectionately known among her colleagues as “E.T.”
From Ichthyopedia: “From 1917 to 1921, [Trewavas] was a student at Reading University College (now Reading University), where she received a BSc honours degree. After graduation she worked for some four years as a science teacher and then attended the University of London, where she received her doctor of science degree in 1934. In 1928 Charles Tate Regan (1878–1943), then director of the British Museum (Natural History), hired her as his research assistant, a position she held until she transferred to the regular staff of the museum in 1935. She collaborated with Regan in publishing studies of fishes of several families collected during the Dana expeditions of 1920–1922 and 1928–1930 and worked on a number of other families of fishes on her own, including the Sciaenidae and Mugilidae, but she is best known for her studies of African cichlids, especially those of Lake Nyasa (now Lake Malawi). She has been recognized for her outstanding career by the American Society of Ichthyologists and Herpetologists (Honorary Foreign Member, 1946), Linnean Society of London (Linnean Medal, 1968; Fellow, honoris causa, 1991), and the University of Stirling (DSc, honoris causa, 1986). Trewavas died at her home near Reading, England, on 16 August 1993, from the effects of a heart attack.”
Over the course of her career, “E.T.” produced more than 120 publications, including books, monographs, scientific papers, and popular articles. She was the sole or first author of 95% of these publications. Even more impressive is the large number of taxa she described or co-described, across 16 different families, that are still valid today. By my count …
