Jack and Barbara Willke got their start on the Catholic speaking circuit talking about the pleasure of sex within marriage. Their daughter would convince them to shift their focus to another hot-button issue. The Willkes’ Handbook on Abortion, and the photographs they distributed along with it, would help kickstart the right-to-life movement.

To see the cover of the Handbook on Abortion, some of the photos the Willkes used, and the brochure “Life or Death,” go to slate.com/handbook.
