Walter Medley Tattersall
He was born in Liverpool, the eldest son of a draper's family. He studied zoology at the University of Liverpool, where he graduated in 1901. Subsequently, he worked as a naturalist for the Irish Fisheries Department under Ernest William Lyons Holt, where he began his studies of crustaceans. In 1909 he became the director of the Manchester Museum and also worked as a tutor in marine biology at the universities of Manchester and Sheffield.
In 1922, he was appointed professor at the University of Cardiff, a post he would hold for the rest of his life. He was highly respected as a teacher in zoology and marine biology and also as a field researcher and taxonomist. Tattersall has an impressive publication record; he is the taxonomic authority for a large number of crustaceans, in particular of mysids and euphausiids. Most of the illustrations in his publications were drawn by his wife Olive.
