Martyn Lloyd-Jones (1899-1981) was born in Wales. He was a dairyman's assistant, a political enthusiast, debater, and chief clinical assistant to Sir Thomas Harder, the King's Physician. But at the age of 27 he gave up a most promising medical career to become a preacher. He had a far-reaching influence through his ministry at Westminster Chapel in London, England from 1938-68. His published works have had an unprecedented circulation, selling in millions of copies.
