Dr. 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 of England's Physician. But at the age of 27 he gave up a most promising medical career to become a preacher... When a spiritual history of the 20th century comes to be written it will be bound to include mention not only the far-reaching influence of Dr. Lloyd-Jones' ministry at Westminster Chapel in London, England from 1938-68, but of the remarkable fact that his published volumes of expository sermons have had an unprecedented circulation for such material, selling in millions of copies.
