Denis O'Donaghue

Denis O'Donaghue (November 30, 1848 – November 7, 1925) was an American prelate of the Catholic Church. He served as Bishop of Louisville from 1910 to 1924.

Biography Early life O'Donaghue was born on a farm in Daviess County, Indiana, to Irish immigrants James and Mary (née Toomey) O'Donaghue. Five of his sisters became religious sisters, and one brother also became a priest. He attended Saint Meinrad Seminary for a year before transferring to Saint Thomas Seminary in Bardstown, Kentucky. In 1871 he entered the Grand Séminaire de Montréal, where he completed his theological studies.

Priesthood O'Donaghue was ordained a priest on September 6, 1874, by Bishop Jacques-Maurice De Saint Palais. His first assignment was as assistant pastor to Rev. Augustus Bessonies at St. John the Evangelist Church in Indianapolis. In 1878, when Silas Chatard became Bishop of Vincennes (renamed the Diocese of Indianapolis in 1898), he named O'Donaghue as chancellor of the diocese.

Episcopal ministry On February 13, 1900, O'Donaghue was appointed auxiliary bishop of Indianapolis and titular bishop of Pomaria by Pope Leo XIII. He received his episcopal consecration on the following April 25 from Archbishop William Henry Elder, with Bishops John Samuel Foley and Thomas Sebastian Byrne serving as co-consecrators, at St. John's Church in Indianapolis. For his efforts and those of the religious sisters and Knights of Columbus in Louisville during the pandemic, General Fred Thaddeus Austin of Camp Zachary Taylor wrote him a public letter of gratitude.

Given his advanced age and ill health, O'Donaghue requested a coadjutor bishop to succeed him, and received 36-year-old John A. Floersh in February 1923. He subsequently resigned as Bishop of Louisville on July 26, 1924, at which time he was also named titular bishop of Lesvi. He celebrated the golden jubilee of his priestly ordination the following September and the silver jubilee of his episcopal consecration in February 1925.

O'Donaghue died in Louisville on November 7, 1925, at age 76.
