This book provides considerable details and bibliographic entries for those women who were the first to step into the scientifc societies devoted to natural sciences in London in the early twentieth century. This work thus gathers together a wealth of material on a question that needs further inquiry and investigation . We owe it to the author to have frmly pointed us in that direction. (Brigitte Van Tiggelen, Metascience, Vol. 32 (3), 2023) It is well suited for researchers interested in womens education, women in the sciences, amateur contributions to the sciences, and the response of scientific societies to changing social conditions. The book can certainly be recommended for a graduate seminar, or perhaps some chapters could be assigned to undergraduates as case studies illustrating the contributions of women in the sciences, both in terms of research and in terms of creating educational and mentor structures to promote and circulate that research.
