T. DeWitt Talmage

The collection contains extensive papers of A.T. Pierson, as well as many of his son's. Among these are letters from C.H. Spurgeon, John Wanamaker, Woodrow Wilson, Helen Keller, Charles Lindbergh, A.A. Hodge, William Henry Green, Hudson Taylor, and many others. There are also several scrapbooks maintained by A.T. Pierson. In addition, there is a significant amount of miscellany, including notes, sermons, and article manuscripts.

Unfortunately, in the case of the miscellany, it is often difficult to distinguish between what was produced by A.T. Pierson and what was produced by his son Delavan. Delavan maintained theological concerns very similar to his father's and was involved in many of the same ministries. He used his father's notes and added to them in his own hand. Further, examination of the scrapbooks reveals that A.T. Pierson had several different styles of handwriting.
