Robert Henry Boll (1875–1956) was a German-born American preacher and theologian whose ministry significantly influenced the Churches of Christ, particularly through his advocacy of premillennial eschatology. Born on June 7, 1875, in Badenweiler, Germany, to Roman Catholic parents Max Boll and Magdalena Ulman, Boll’s early life was marked by frequent moves, including to Basel, Switzerland, and Karlsruhe, Germany, before settling in Freiburg. His father died when he was ten, and his mother remarried when he was 14, prompting Boll to emigrate to the United States in 1890 with a maternal aunt, initially settling in Zanesville, Ohio. Converted to Christianity on April 14, 1895, through immersion by Sam Harris near Nashville, Tennessee, he soon enrolled in the Nashville Bible School (later Lipscomb University), studying under James A. Harding and David Lipscomb, though he left in 1900 to pursue preaching full-time. Boll’s preaching career began in earnest across Tennessee, Texas, and Kentucky, gaining prominence when he became front-page editor of the Gospel Advocate from 1909 to 1915. His premillennial views—emphasizing Christ’s return before a literal thousand-year reign—sparked controversy, leading to his forced resignation in 1915 due to opposition from the journal’s board. In 1916, he assumed editorship of Word and Work, a publication he led for 40 years until his death, using it to promote his eschatological stance and train preachers through Bible classes and tent meetings, notably at Portland Avenue Church of Christ in Louisville, Kentucky, where he ministered from 1904 onward (except 1910–1911). A prolific writer, he authored works like The Kingdom of God and Lessons on Hebrews, and his influence grew despite fierce opposition from figures like Foy E. Wallace Jr., contributing to a significant division within the Churches of Christ by the 1930s. Boll died on April 13, 1956, in Louisville, leaving a legacy as a preacher whose steadfast convictions, though divisive, enriched evangelical thought through his focus on Scripture and personal faith. Personal details about his family are sparse, but he remained a towering, if polarizing, figure in Restoration Movement history.
