We all know about Albert Einstein, Galileo Galilei, and Charles Darwin. Most people have heard of Isaac Newton and possibly Nicolaus Copernicus and Robert Oppenheimer. As for women, the name Marie Curie is at least vaguely familiar, but that's about it.
Most people only know the names of a few scientists anyway.
But even among scientists and historians of science, who know more scientists' names than average, women just aren't part of the story. No women are considered truly indispensible to the progress of science as several men have been over the centuries. Lise Meitner had to sneak into the physics building and crawl under the auditorium chairs to hear seminars because women were not allowed in the physics building. Women were ruthlessly excluded from the inner circles of these disciplines. That is not meant to detract from their success in any way.
