Thomas Hicks, an American painter, born in Newtown, Bucks co., Pa., Oct. 18, 1823. He attempted portrait painting in his 15th year, and in 1838, after copying the casts in the Pennsylvania academy of fine arts, entered the life and antique schools of the national academy of design in New York, to whose annual exhibition in 1841 he contributed a picture of the "Death of Abel." For several years he painted portraits and compositions, and in 1845 went to Europe. He passed three years in Italy, chiefly at Rome, afterward studied under Couture in Paris, where he remained about a year, and after a brief residence in England returned to New York in 1849. He has since devoted himself principally to portrait painting, but has occasionally produced landscapes and figure pieces. Among his portraits are those of Dr. Kane in the cabin of the Advance, Longfellow, Margaret Fuller, Henry Ward Beecher, Edwin Booth as Iago, and a large picture of the " Contemporaneous Authors of America." In 1865 he published a eulogy on Thomas Crawford.
