Bard Thompson (1925-1987) received a PhD at Union Theological Seminary in 1952. Before coming to Lancaster Seminary in 1961 he served on the faculties of Candler School of Theology and the Divinity School of Vanderbilt University. He is the author of Liturgies of the Western Church (1961) and co-author with Howard Paine of Book of Prayers for Church and Home (1962). His lecture "The Heidelberg Catechism and the Mercersburg Theology" constituted his inaugural address as professor of church history at Lancaster Theological Seminary. The two other Thompson essays were given at Mission House Theological Seminary in June 1961 as part of the celebration of the centennial of that seminary.
