Mabel Elizabeth Tomlinson and Isabel Ellie Knaggs: two overlooked early female Fellows of the Geological Society

Abstract

AbstractThe first female Fellows of the Geological Society of London were elected in May 1919. Brief biographies were documented by Burek in 2009 as part of the celebrations for the bicentenary of the Geological Society. While some of those women were well known (e.g. Gertrude Elles and Ethel Wood), others had seemingly been forgotten. In the decade since that publication, information has come to light about those we knew so little about. There are, however, still some details evading research. From 1919 until 1925, 33 women were elected FGS, including Isobel Ellie Knaggs (1922) and Mabel Tomlinson (1924). Mabel Tomlinson had two careers, and is remembered both as an extraordinary teacher and a Pleistocene geologist. She was awarded the Lyell Fund in 1937 and R.H. Worth Prize in 1961, one of only 13 women to have received two awards from the Geological Society. She inspired the educational Tomlinson–Brown Trust. Isabel Knaggs was born in South Africa and died in Australia but spent all her school, university and working years in England. She made significant contributions to crystallography, working with eminent crystallography scientists while remaining a lifelong FGS. The achievements of Tomlinson and Knaggs are considerable, which makes their relative present-day obscurity rather puzzling.
