This work reaffirms women's substantial contributions to scientific knowledge throughout the ages, revisiting names such as Hypatia of Alexandra, astrologer and philosopher Hildegaard of Bingen, Lady Mary Montegu - who developed inoculation against smallpox, the chemist Marie Levoissier, Caroline Hershel - a renowned astrologer, Ada Lovelace - whose work contributed to the beginnings of computer science, Mary Somerville "the queen of 19th-century science" and, of course, Marie Curie. In doing so she both reinforces women's contributions to history and outlines the precedents for women making great strides in contemporary science.
