From A Compendium of Irish Biography, 1878
Dean, Hugh, an Irish artist in the 18th century, who early attained considerable excellence in landscape. The then Lord Palmerston enabled him to visit Rome to complete his studies, but was ultimately obliged to abandon him on account of the irregularity of his conduct. In 1780 Dean gave an exhibition of his paintings in London. He soon afterwards became a Methodist preacher. He is supposed to have died in 1784.
