Short answers, pulled from the story.
George Peter Alexander Healy was an American portrait painter born in Boston on the 15th of July, 1813, and died in Chicago on the 24th of June, 1894. He was one of the most prolific portrait painters of the nineteenth century, with sitters ranging from multiple American presidents to Pope Pius IX, Franz Liszt, and European royalty.
Healy studied in Europe after leaving Boston in 1834. In Paris he worked under Antoine-Jean Gros and came under the influence of Thomas Couture. Before going abroad, Jane Stuart, daughter of Gilbert Stuart, guided him early in his career and introduced him to Thomas Sully.
Healy painted portraits of all the presidents of the United States from John Quincy Adams through Ulysses S. Grant. This series was painted for the Corcoran Gallery in Washington, D.C.
Healy's 1877 portrait of a young Lincoln served as the model for a Lincoln postage stamp. The stamp was issued on the 12th of February, 1959, the 150th anniversary of Lincoln's birth, following a suggestion by Katherine McCook Knox.
Webster's Reply to Hayne is a large historical painting completed by Healy in 1851 and now hanging in Faneuil Hall in Boston. It contains one hundred and thirty individual portraits within a single canvas.
Healy's works are held at several institutions, including the Corcoran Gallery in Washington, D.C., the Smithsonian Institution, the Metropolitan Museum of Art in New York, Faneuil Hall in Boston, and the Newberry Library in Chicago, which holds forty-one paintings he donated in 1887.
