Lady Science is an online magazine focusing on women and gender in the history and popular culture of science, technology, and medicine. Each year, our writers and editors publish 22 critical essays on these topics, which we collect into an edited volume available as a free ebook. This second volume of Lady Science, containing essays from 2016-2017, is part of our mission to make important and productive scholarship about women and gender available for free to students and the general public. The second anthology continues to carry out our mission to write women back into the history of science, technology, and medicine and to expose the structural reasons that they have been excluded or obscured. This entails not only vital recovery work in the area of biography and professional histories of women scientists, but also the application of feminist theory to these histories in ways that help us account for the structural oppressions that condense around race, gender, class, and disability.
