Arthur Tappan Pierson (1837-1911) was an American Presbyterian pastor, early fundamentalist leader, and writer who preached over 13,000 sermons, wrote over fifty books, and gave Bible lectures as part of a transatlantic preaching ministry that made him famous in Scotland and England. He acted as the elder statesman of the student missionary movement and was the leading evangelical advocate of foreign missions in the late 1800s. Since 1888 he was editor of the Missionary Review of the World, and was lecturer on missions in Rutgers College in 1891 and Duff lecturer in Scotland in 1892. One of his most significant books was, In Christ Jesus (1898), where he came to the conclusion that this brief phrase "in Christ Jesus" a preposition followed by a proper name was the key to understanding the entire New Testament. He was a consulting editor for the original Scofield Reference Bible (1909). His other works include: The Crisis of Missions (1886), Many Infallible Proofs: Chapters on the Evidences of Christianity (1886), Evangelistic Work in Principle and Practise (1887), George Müller of Bristol (1889) and The Divine Enterprise of Missions (1891).
