Candidly, you are unlikely to have heard of many of the women described in this book. Male scientists from that century are often forgotten today, unless they really were the giants in their fields. So it is that much harder for any females to be remembered now.The book restricts itself to Britain and the US. Because despite the well described discrimination against the women in the book, those countries were the most receptive to female researchers. A telling commentary of the social mores of that time, even amongst the most educated and supposedly least prejudiced males - the faculty of the universities.Creese must have spent years delving into musty boxes of records. Any of you who have done research will appreciate the lengths she must have gone through to unearth the raw data, like the biographies. If some of these seem sparse, little wonder.
