Dictionary of National Biography, 1885-1900/Mannin, James
MANNIN, JAMES (d. 1779), flower-painter, was a native of France. He settled in Dublin, where he practised as a flower-painter, and obtained such distinction in his ornamental compositions that in 1746 he was appointed to the office of master in the class of ornament and flower-painting in the newly established drawing academy of the Dublin Society in Shaw's Court, Dublin. Many artists who subsequently attained distinction were his pupils. Mannin was a contributor to the exhibitions of the Society of Artists in Ireland in 1765 and other years. He died in Dublin in 1779.
