George Peter Alexander Healy (July 15, 1813 - June 24, 1894) was a Boston-born American artist who is known for his paintings of important 19th century American figures such as John Quincy Adams, Ulysses Grant, Daniel Webster, Henry Clay, John Calhoun, and William Seward.
His 1868 painting The Peacemakers depicting an historic March 28, 1865 strategy session on the steamer River Queen is a quite famous as it represents the war's only three-way meeting between President Lincoln, General Grant, and General Sherman along with Rear Admiral David Dixon Porter. The original painting was destroyed by a fire. In 1922, a copy was discovered in a family storeroom in Chicago. The Official Portrait of George H. W. Bush shows him standing in front of the painting. The painting was displayed in the Treaty Room from the Kennedy through the George W. Bush presidencies. The Obama administration moved it to the private President's Dining Room. There is also a copy of the painting at the Pentagon. Robert Todd Lincoln considered this likeness of his father to be the "most excellent in existence". His 1860 portrait of Abraham Lincoln without a beard is also rather famous.
His 1866 portrait of William Tecumseh Sherman was used as the cover artwork for the game Shiloh: Bloody April, 1862.
