Rating: 5 Stars Themes: Non-Fiction, Psychology, STEM Thoughts: I received an advance review copy for free, and I am leaving this review voluntarily. It was great to learn about the women behind the theories and research in a historically male dominated field with a broad range of theories covered. I liked the brief portraits chapters, both for the early twentieth century and modern age, mixed in with the specific researchers and their work/theories. I also liked the photos at the end of some of the researchers, especially Anna Freud and Melanie Klein who I had read a lot about previously but never had a face to put to the name. Finally, the glossary is very helpful and I found the title entertaining (So … what does that mean? A glossary of frequently used but kind of weird terms).
