Geoffrey Parrinder (1910 – 2005) was a British scholar, professor and Methodist minister whose reference works on world religions are appropriate for both lay and learned readers.
Parrinder is particularly strong on African and non-Christian religions, although his more recent Encyclopedia of Christianity strikes a good balance between conciseness and breadth of coverage.
He spent almost two decades as a missionary along the western coast of Africa from the 1930s to 50s, and later, from the 1950s to 70s, taught at King’s College London. One of his more famous students there was “the future Anglican Archbishop Desmond Tutu.”¹
