Famous Women Scientists

Notable Women in Science, Medicine, and Math

British and American polls say that few people can name even one famous woman scientist. Here are some women in the sciences including medicine and mathematics. You may recognize some of these famous women scientists; others may be new to you and worth further exploring. They're listed alphabetically over several pages, though I put Marie Curie at the top because, let's face it, that's the one woman scientist most people know. Click through to the rest of the pages so you don't miss the others.
