When Vera Rubin was a 10-year-old girl in Washington, D.C., she watched enchanted as the night sky rotated outside her north-facing bedroom window. At 14, she made her first telescope from a cardboard tube. Her ardor was so intense that she won a scholarship to Vassar and was its only astronomy graduate in 1948.

She applied to Princeton’s renowned astronomy graduate program but found that it didn’t accept women. She finally earned a doctorate at Cornell and Georgetown universities—then discovered that male astronomers wouldn’t let her into their projects.

On her own, she began studying the rotation of galaxies—and made a historic breakthrough. She found that outer fringes of the spirals travel too fast to be balanced by gravity of the visible mass at their centers. Therefore, galaxies must contain invisible “dark matter” that supplied the extra mass.

Reluctantly, the scientific world slowly accepted her conclusion that nine-tenths of the universe is an unseen mystery. Belatedly, she was honored for her work. Belatedly, Princeton finally opened its graduate astronomy study to women in 1975.

National Geographic recently listed six other female scientists who made landmark advances but were pushed aside by the male-dominated scientific establishment. To wit:

Thank heaven, sexism in science finally is disappearing as young women flood U.S. universities and gradually gain equal access to research work. West Virginia’s celebrated National Youth Science Camp is attended by multitudes of brilliant girls just out of high school. Old-style discrimination must be stamped out entirely.
