Meet Margaret Crane: The “silent” revolutionary.

She invented the first home pregnancy kit that allows women to quickly know whether they are pregnant or not and seek medical care or an abortion, sold the rights for $1 dollar and continued to work as a publicist.

Today eight out of 10 women learn they are pregnant from a drugstore device. But her name was unknown until 2012, when The New York Times published an article searching for the creator of the first kit.

Women Across Frontiers’ editors, Karina Mirochnik and Sylvia Maier met with her at a cafe in Manhattan and asked her if she realized the sort of revolution she brought to women’s lives.
