Isaac Massey Haldeman

Born in 1845 in Concordville, Pennsylvania, Isaac Massey Haldeman served in the Union Army during the Civil War and later entered the Baptist ministry. After pastoral work in Pennsylvania and at Delaware Avenue Baptist Church in Wilmington, Delaware, he was called in 1884 to the First Baptist Church in the City of New York.

He remained pastor there until his death in 1933, becoming widely known as a preacher, conference speaker, and prolific religious author. His books and sermons often focused on Bible exposition, prophecy, and evangelical doctrine, and many were circulated far beyond his own congregation.

Haldeman wrote in a clear, forceful style that aimed to make Scripture understandable to ordinary readers. For listeners interested in classic Protestant preaching and devotional Bible teaching, his work offers a window into American evangelical life from the late 19th and early 20th centuries.
