Published to accompany the 2013 landmark exhibition at the Grolier Club, this catalogue explores the legacy of thirty-two remarkable women whose accomplishments in physics, chemistry, astronomy, mathematics, computing, and medicine contributed to the advancement of science. More than 150 original items are pictured and described, including books, manuscripts, periodicals, offprints, dissertations, and laboratory apparatus (such as that used by Marie Curie during her earliest work on radioactivity), providing a remarkable overview of the scientific contributions of this eminent group.
