Samuel Beatty was born in Mifflin County, Pennsylvania, on December 16, 1820. His family moved to Stark County, Ohio, in 1829, settling on the farm in Jackson Township where Beatty spent his entire life, except for his service in two wars. Having little formal education, Beatty enlisted in 1846 and served a year as first lieutenant of the 3rd Ohio Infantry in the Mexican War. In 1857 he was elected sheriff of Stark County and was reelected in 1859. On April 27, 1861, he was elected captain of Company A, 19th Ohio Infantry, and colonel of the regiment on May 29. He fought competently at Shiloh and in the "siege" of Corinth, was in command of the brigade at Perryville and Murfreesboro, and was promoted to brigadier general of volunteers on November 29, 1862. At Chickamauga his brigade was in H. P. Van Cleve's division of the XXI Corps and, in the Chattanooga campaign, in Thomas J. Wood's division of Granger's IV Corps, which took part in the famous storming of Missionary Ridge. Beatty participated in the Atlanta campaign and in the battles of Franklin and Nashville. During this last operation he was in divisional command, Wood having been advanced to direction of the IV Corps. On March 13, 1865, General Beatty was brevetted major general of volunteers for "long and gallant service in the field" and, on January 15, 1866, was honorably mustered out. The records do not reveal why he did not receive a full major generalcy. He returned to his farm in Ohio to live uneventfully: four years before his death on May 26, 1885, he was listed unpretentiously in a county history as "Farmer; P. O. Massillon." General Beatty was buried in the Massillon City Cemetery.
