Dictionary of National Biography, 1885-1900/Adolph, Joseph Antony
ADOLPH, ADOLF, or ADOLPHE, JOSEPH ANTONY (1729–1762), painter, born at Nikolsburg in Moravia, was the son of Joseph Frank Adolph, painter to Prince C. Max von Dietrichstein. He came to England in 1745; he painted an equestrian portrait of George III when Prince of Wales, which was engraved by Baron. The engraving was published in 1755. During his stay in England, which lasted for some years, Adolph is said to have been engaged chiefly as a portrait painter; but on his return to Austria he was employed in the decoration of interiors, adorning walls with frescoes, and painting the ceilings of large saloons. Three altar-pieces by him are in the collegiate church of Nikolsburg. He died at Vienna, 17 Jan. 1762.
