Donald F. Durnbaugh (1927–2005) was a noted historian of the Church of the Brethren who published more than 200 books, articles, reviews, and essays on its history. In the words of Dale Brown, with whom he taught at Bethany Theological Seminary, Durnbaugh was "the dean of Brethren historians." He was also considered a leading authority on other Anabaptist religious movements.
