Cooper (John Gilbert), poet, b. Thurgaton Priory, Notts, 1723. Educated at Westminster School and Trinity College, Cambridge. An enthusiastic disciple of Lord Shaftesbury. Under the name of "Philaretes" he contributed to Dodsley's Museum. In 1749 he published a Life of Socrates, for which he was coarsely attacked by Warburton. He wrote some poems under the signature of Aristippus. Died Mayfair, London, 14 April, 1769. Cooper (Peter), a benevolent manufacturer, b. N. York, 12 Feb. 1791. He devoted over half a million dollars to the Cooper Institute, for the secular instruction and elevation of the working classes. Died 4 April, 1883. Cooper (Robert), Secularist writer and lecturer, b. 29 Dec. 1819, at Barton-on-Irwell, near Manchester. He had the advantage of being brought up in a Freethought family. At fourteen he became teacher in the Co-operative Schools, Salford, lectured at fifteen, and by seventeen became an acknowledged advocate of Owenism, holding a public discussion with the Rev. J. Bromley. Some of his lectures were published--one on Original Sin sold twelve thousand copies--when he was scarcely eighteen. The Holy Scriptures Analysed (1832) was denounced by the Bishop of Exeter in the House of Lords. Cooper was dismissed from a situation he had held ten years, and in 1841 became a Socialist missionary in the North of England and Scotland. At Edinburgh (1845) he wrote Free Agency and Orthodoxy, and compiled the Infidel's Text Book. About '50 he came to London, lecturing with success at John Street Institution. In '54 he started the London Investigator, which he edited for three years. In it appears his lectures on "Science v. Theology," "Admissions of Distinguished Men," etc. Failing health obliged him to retire leaving the Investigator to "Anthony Collins" (W. H. Johnson), and afterwards to "Iconoclast" (C. Bradlaugh). At his last lecture he fainted on the platform. In 1858 he remodelled his Infidel Text-Book into a work on The Bible and Its Evidences. He devoted himself to political reform until his death, 3 May, 1868.
