by John Theodore Mueller
Born near Janesville, Minnesota, on April 5, 1885, John Theodore Mueller followed the traditional Lutheran Church—Missouri Synod path of study through Concordia schools in St. Paul, Milwaukee, Fort Wayne, and finally Concordia Seminary in St. Louis, graduating in 1907. Early in ministry he served congregations and also pursued further study while living in the South.
Mueller became best known as a professor at Concordia Seminary in St. Louis, where he taught theology for many years and earned a reputation for serious scholarship and careful classroom work. He also wrote, translated, and edited a wide range of books and articles, including works on Christian doctrine, church history, missions, and notable Christian figures.
Among readers today, he is especially remembered for Christian Dogmatics and for helping make important Lutheran theological writings available in English. He died in 1967, leaving behind a substantial body of work that continued to serve pastors, students, and lay readers after his death.
