William MacDonald (1917-2007) had, for more than forty years, written directly about the key issues of Christianity. Leaving a promising business career as an employed investment analyst with First National Bank of Boston "at the foot of the Cross", he had traveled worldwide, proclaiming the unsearchable riches of Christ.

His more than over eighty-four works published in North America are characterized by a clarity and economy of words that only comes by a major time investment in the Word of God.

MacDonald graduated with an AB degree from Tufts College (now University) in 1938 and an MBA degree from Harvard Business School in 1940. During the 1940's he was on active duty in the US Navy for five years.

He was President of Emmaus Bible College, a teacher, preacher, and Plymouth Brethren theologian alongside his ministry as a writer. He was a close friend and worker with O.J. Gibson.

MacDonald last resided in California where he was involved in his writing and preaching ministry. He went to be with the Lord in 2007.
