Francis August Schaeffer (January 30, 1912 – May 15, 1984) 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 (which prefers, e.g., rational thought and religious experience over doctrinal pronouncements by leaders or following religious traditions), 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.
