Francis Schaeffer, American pastor, theologian, and philosopher (born 1912)

Francis August Schaeffer was an American evangelical theologian, philosopher, and Presbyterian pastor. He co-founded the L'Abri community in Switzerland with his wife Edith Schaeffer, née Seville, a prolific author in her own right. Opposed to theological modernism, Schaeffer promoted what he claimed was a more historic Protestant faith and a presuppositional approach to Christian apologetics, which he believed would answer the questions of the age.
