American cardinal, born in Brooklyn, NY, on the 20th of March 1810. He graduated at Mt. St. Mary’s College, Emmitsburg, MD, in 1827, studied theology there, was ordained a priest in 1834, and in 1837, after two years in the college of the Propaganda at Rome, became rector of St. Joseph’s, New York City, a charge to which he returned in 1842 after one year’s presidency of St. John’s College (afterwards Fordham University), Fordham, NY, then just opened. In 1844 he was consecrated bishop of Axieren in partibus, and was made coadjutor to Bishop Hughes of New York with the right of succession; in 1847 he became bishop of the newly created see of Albany; and in 1864 he succeeded to the archdiocese of New York, then including New York, New Jersey, and New England. In April 1875 he was invested as a cardinal, with the title of Sancta Maria supra Minervam, being the first American citizen to receive this dignity. He attended the conclave of 1878, but was too late to vote for the new pope. In May 1879 he dedicated St. Patrick’s Cathedral in New York City, whose cornerstone had been laid by Archbishop Hughes in 1858. Archbishop Corrigan became his coadjutor in 1880 because of the failure of McCloskey’s always delicate health. The fiftieth anniversary of his ordination to the priesthood was celebrated in 1884. He died in New York City on the 10th of October 1885. He was a scholar, a preacher, and a man of affairs, temperamentally quiet and dignified; and his administration differed radically from that of Archbishop Hughes; he was conciliatory rather than polemic and controversial, and not only built up the Roman Catholic Church materially, but greatly changed the tone of public opinion in his diocese toward the Church.
