John Landis Ruth '48

John L. Ruth is a historian, author, and longtime church leader whose life’s work has been devoted to preserving and sharing the stories of Mennonite faith, peace, and community. Through decades of research, writing, teaching, and pastoral service, John has helped generations understand how history can guide faithful living in the present.

“History matters because it helps us remember who we are and whose we are,” John has shared. His academic journey led him to study English and history, including doctoral work at Harvard University, and to teach both in the United States and abroad.

Through his many books, documentaries, and historical tours, John has built bridges across generations and across diverse communities. His work reflects a deep commitment to lifelong learning, peacemaking, and Christ’s transforming love—and to reminding us that the stories we inherit are a gift meant to ground and shape our witness today.

Hans Leaman '96

Hans Leaman ’96 is the Academic Dean and an Associate Professor of History at Sattler College in Boston, where he helps lead a classical Christian liberal arts program rooted in the values of the early church and the Anabaptist tradition. His work focuses on church history, Anabaptism, and the ways faith, migration, and discipleship shape Christian communities across time. Hans is also a writer and speaker, recently presenting at the Mennonite World Conference in Switzerland during the 500 Years of Anabaptism commemoration.

“Lancaster Mennonite played a key role in shaping how I understand the world and my place in it,” Hans shared. “Being surrounded by teachers with global experience helped me imagine a faith that is rooted, thoughtful, and outward-looking.”

Through his teaching, writing, and leadership, Hans seeks to form students with empathy, curiosity, and a deep sense of connection to God’s work across history.
