Henry K. Moeller (December 11, 1849 – January 5, 1925) was an American prelate of the Catholic Church. He served as bishop of the Diocese of Columbus in Ohio (1900–1903) and archbishop of the Archdiocese of Cincinnati in Ohio (1904–1925). Biography Early life Henry Moeller was born on December 11, 1849, in Cincinnati, Ohio, to Bernard and Teresa (née Witte) Moeller, who were immigrants from Westphalia. He was the oldest of seven children; one of his sisters became a nun, and two brothers also became priests. His father worked as a cabinet maker and carpenter before becoming a bricklayer and building contractor. Henry Moeller was baptized by Father John Henry Luers the day after his birth, and received his early education at the parochial school of St. Joseph Parish in the West End of Cincinnati. In 1863, Moeller entered St. Xavier College in Cincinnati, graduating with highest honors in 1869. He was then sent by Archbishop John Purcell to study philosophy and theology at the Pontifical North American College in Rome. In his competitive examinations, he won three first prizes in theology. Moeller was ordained a subdeacon on November 2, 1875, and a deacon on the following November 10. Priesthood On June 10, 1876, Moeller was ordained to the priesthood for the Archdiocese of Cincinnati by Archbishop Giulio Lenti at the Basilica of St. John Lateran in Rome. That same year he received his Doctor of Divinity degree from the Urban College of Propaganda in Rome. Following his return to Ohio, Moeller was appointed pastor of St. Patrick Parish in Bellefontaine in September 1876. He then served as a professor at Mount St. Mary's Seminary of the West in Norwood, Ohio, from 1877 to 1879. In November 1879, Moeller was granted a leave of absence from the Archdiocese of Cincinnati to assist Bishop Silas Chatard of the Diocese of Vincennes in Indiana. He served as secretary to Bishop Chatard until 1880, when he was recalled to Cincinnati by Archbishop William Elder to serve as his own secretary. Moeller served as chancellor of the archdiocese from 1886 to 1900. Bishop of Columbus On April 6, 1900, Moeller was appointed the third bishop of the Diocese of Columbus by Pope Leo XIII.
