Antonio Grego, a native of Como, settled in London before 1821 as a looking-glass manufacturer, the firm becoming Susan Grego & Sons in 1839, and Charles & Joseph Grego in 1845. His grandson Joseph was born on 23 September 1843 at no. 23 Granville Square, Clerkenwell. He became an art historian and was specialised in the work of James Gillray, Thomas Rowlandson, George Morland, and George Cruikshank. He was chiefly responsible for an edition of James Gillray’s works, The Works of J. G. the Caricaturist, with the History of his Life and Times (1873) and he edited Rowlandson the Caricaturist (1880), which became standard reference books. Grego also wrote the History of Parliamentary Elections (1886). He was a director of Carl Hentschel’s firm of photo-engravers and a substantial shareholder in the firm of Kegan Paul, and of the Graphic Company. Grego died in January 1908 at Granville Square where he had lived all his life.
