Marie Tharp began her career at a time when few women became scientists. Because of her gender, she wasn’t allowed on the ships that collected the seafloor data that she used to make her maps; she didn’t set foot on a research cruise until 1968 (sounds familiar).

Her early evidence of seafloor spreading was dismissed as “girl talk” by her colleague Bruce Heezen before they started their decades long fruitful collaboration.
