G. Campbell Morgan (1863-1945) was a pastor and leading Bible scholar. He was a contemporary of Rodney "Gipsy" Smith and preached his first sermon at age 13. A few years after Morgan was ordained to the Congregational ministry, D. L. Moody invited him to teach at the Moody Bible Institute. Morgan became the director of Northfield Bible Conference after Moody.
He was the pastor of Westminster Chapel in London from 1904 to 1919 and then from 1933 to 1943, pausing for a brief period to work at Biola in Los Angeles. In 1939, Morgan began to mentor Martyn Lloyd-Jones, who would eventually become his successor at Westminster Chapel.
Morgan's essay entitled The Purposes of the Incarnation is included in a collection called The Fundamentals, a set of 90 essays that is widely considered to be the foundation of the modern Fundamentalist movement. Morgan was a prolific author, he wrote many works including The Analyzed Bible, Discipleship, The True Estimate of Life and How to Live, and many more.
