About Denis J. O'Connell
Lived 1849 – 1927 (aged 77). Denis J. O'Connell was a catholic priest and catholic bishop.
Denis Joseph O'Connell (January 28, 1849 – January 1, 1927) was an American Catholic bishop and academic administrator. He served as rector of the Pontifical North American College in Rome (1885–1895) and the Catholic University of America in Washington, D.C. (1903–1909). He later served as an auxiliary bishop of the Archdiocese of San Francisco (1908–1912) and Bishop of Richmond (1912–1926).
Early life and education A native of Ireland, Denis Joseph O'Connell was born on January 28, 1849, in Donoughmore, County Cork. He was the third of twelve children born to Michael and Bridget O'Connell. One brother, Patrick, later served in the South Carolina House of Representatives (1868–1872) and two sisters, Annie and Joanna, became members of the Sisters of Mercy and Daughters of Charity. Three of Michael's brothers—Jeremiah, Joseph, and Lawrence—were missionary priests and had come to South Carolina several years earlier.
Denis received his early education at St. Mary's College, a boys' school which his uncle Jeremiah had founded in 1851. However, the school and the O'Connell home were destroyed during the capture of Columbia in February 1865. The O'Connell family then moved to Fort Mill, near Charlotte, North Carolina. Jeremiah would later play an instrumental role in the establishment of Belmont Abbey College, purchasing land for the Benedictines to start a new Catholic educational institution in the Carolinas. While there, he was recruited for the Apostolic Vicariate of North Carolina by its new bishop, James Gibbons. This was the beginning of an intimate and lifelong friendship between the two men, leading one journalist to describe them as "[Gibbons] and his Father Achates O'Connell." In 1872, after Gibbons became Bishop of Richmond, he sent O'Connell to continue his studies in Rome. O'Connell resided at the Pontifical North American College while taking courses at Pontificio Collegio Urbano de Propaganda Fide. According to Louis Hostlot, then vice-rector of the American College:
"Mr. O'Connell has given the greatest satisfaction during his course. His talent is remarkable. At his examination for the degree of D.D., his success has been so marked, that the degree was conferred on him by the Cardinal & professors with acclamation, they refusing to vote by ballot as is usual on such occasions." When Gibbons became Archbishop of Baltimore in October 1877, O'Connell was sent to Rome to retrieve his pallium. O'Connell also served as secretary to George Michael Conroy, the Apostolic Delegate to Canada, during his tour of U.S. dioceses in 1878. During the council, his uncle Joseph O'Connell, then pastor of St. Michael's Church in Brooklyn, served as a theologian to Bishop John Loughlin. After the close of the council in December 1884, Denis was again sent to Rome to obtain approval of the council's documents from Pope Leo XIII.
Pontifical North American College
Following the death of Louis Hostlot, the bishops on the Pontifical North American College's executive board submitted three names to Rome to succeed him as rector—O’Connell, interim rector Augustine Schulte, and William Kieran of Philadelphia. The Congregation for the Propagation of the Faith (which then oversaw the college) nominated O'Connell on June 8, 1885, In addition to his administrative duties, he was tasked with obtaining papal audiences for American visitors and hosting American prelates who were visiting Rome. He also served as an unofficial agent of American bishops, representing their interests with Vatican officials. He became closely identified with the liberal faction of American bishops, led by Gibbons, Archbishop John Ireland, and Bishop John J. Keane.
On June 7, 1895, O'Connell submitted his resignation as rector (effective November 1) Canonist Richard Lalor Burtsell claimed that Leo XIII had become enraged when he learned O'Connell had repeated a rumor that Cardinal Francesco Satolli was the pope's illegitimate son. A biographer of Gibbons argued the principal reason was O'Connell's liberal views, which also led to the dismissal of Bishop Keane as rector of the Catholic University of America the following year. Shortly afterward, Conaty was appointed Bishop of Monterey–Los Angeles, clearing the way for O'Connell. On January 12, 1903, six months before his death, Leo XIII appointed O'Connell as rector. In a letter to Gibbons, Archbishop Ireland remarked, "What a revolution in the temper of Rome there is implied in his nomination!" O'Connell also oversaw significant growth in the student body, rising from 91 in his first year to 224 in the 1907–1908 academic year.
Following the tradition of the previous two rectors, who were bishops, Pope Pius X appointed O'Connell to the honorary position of Titular Bishop of Sebaste on December 16, 1907.
Episcopal career Auxiliary Bishop of San Francisco After declining the request of Archbishop Patrick William Riordan to appoint Edward Joseph Hanna as a coadjutor bishop of the Archdiocese of San Francisco, Pius X instead named O'Connell an auxiliary bishop of San Francisco on December 25, 1908. By O'Connell's final year as bishop in 1926, there were 44,000 Catholics, 110 churches, 105 priests, and 32 parochial schools.
Retirement and death In November 1925, Cardinal Gaetano de Lai of the Sacred Consistorial Congregation (now the Dicastery for Bishops) wrote to O'Connell to seek his retirement as Bishop of Richmond. O'Connell subsequently submitted his resignation, which was accepted by Pope Pius XI on January 15, 1926.
