This 1912 portrait of John Ericsson by Arvid Frederick Nyholm (after Mathew Brady) hangs in the National Portrait Gallery in Washington DC.
"Before he came to the United States in 1839, the Swedish-born engineer and inventor John Ericsson revolutionized navigation with his development of the screw propeller, He achieved fame during the Civil War when he designed the ironclad warship Monitor, the federal response to the threat of the Confederate ironclad Virginia (the refitted USS Merrimac) , Ericsson, posing with a model of his 'tin can on a raft,' always worked alone and had previously perfected engines for many purposes, including fire engines and a steam locomotive. He later developed the forerunner of the modern naval destroyer"-- The National Portrait Gallery
