Gerta Keller (born 1945) is a paleontologist who contests the Chicxulub crater as the location of the meteorite impact, postulated as the cause of the Cretaceous–Tertiary extinction event 65 million years ago by the Alvarez hypothesis. Keller is currently a professor of Geosciences at Princeton University.
Keller was raised in Switzerland on a dairy farm, the sixth of 12 children. She grew up in poverty; the unheated room in which she shared a bed with her sister who grew icicles inside the room during the winter. In the one-room schoolhouse where she was educated, boys were given training in math and science while girls were taught cooking and cleaning, the skills they would need to be proper housewives. Her hunger for knowledge led her to read the textbooks assigned to her elder siblings, and she would prepare summaries of the material for her brothers and sisters.
She attended a vocational school starting at age 14 and learned sewing. There she organized a protest against rules that required female students to wear skirts, as she rode her bicycle three miles each way to school and wanted to be able to protect herself from the cold. The female students won the right to wear pants from then on.
