Johann Michael Reu
Johann Michael Reu was born at Diebach, in Bavaria, Germany. He was the youngest of ten children. His father died when Reu was only two years old. Reu studied from 1887-1889 at the nearby Neuendettelsau Mission Institute (Neuendettelsauer Missionsgesellschaft) which had been founded by Wilhelm Loehe in 1841.
He was ordained a Lutheran minister at age 20 and emigrated to the United States where he first served as an assistant pastor in Mendota, Illinois. He subsequently was called to serve as pastor of Immanuel Lutheran Church in Rock Falls, Illinois. In 1899, he joined the faculty of Wartburg Theological Seminary in Dubuque, Iowa, where he taught until his death in 1943. 
In 1902, Reu became an American citizen. Reu was awarded a Doctorate in Theology from the University of Erlangen-Nuremberg in 1910. Reu also received an honorary Doctorate of Literature from Capital University in Columbus, Ohio in 1926,. Reu was a prolific author of 66 books, covering nearly all topics in Christian life, as well as more than 3000 published book reviews.
