John Williamson Nevin (1803-86) and Philip Schaff (1819-93) were professors at Mercersburg Seminary of the German Reformed Church, Nevin being among the leading American Protestant theologians of his day and Schaff quickly rising to become the nineteenth century's premier church historian. Emanuel V. Gerhart (1817-1904) was another leading teacher in the German Reformed church, teaching and writing at several denominational institutions from the 1840s until the close of his career.
David W. Layman earned his PhD in Religion from Temple University in 1994. Since then, he has been a lecturer in religious studies and philosophy at schools in south central Pennsylvania and has researched and written several articles on the Mercersburg movement.
