The Walter Russell Lambuth collection reflects the Bishop's activities outside the United States in a series of manuscripts, articles and letters. There is one typed manuscript of his book, Medical Missions: The Twofold Task. There is a good chance that most, if not all, of the other typed manuscript articles of Lambuth's trips around the world were published by the Southern Methodist Church in their various periodicals. The correspondence is addressed to family, friends, colleagues and associated groups. Clippings are either death notices and/or tributes for both Lambuth and his wife.

This collection consists of slides of the photographs of John Wengatz. Most of the photos are from the later part of John's life, and the majority of the photos are in color. The collection contains approximately 340 photographs of different mission projects in Africa, and about 360 pictures of vacations to South Carolina, England, Belgium, and Portugal, as well as John's home in the United States.
