Description
John Ericsson Autograph Letter Signed. Two pages, two-sided, n.p., October 18, 1858. Swedish inventor and mechanical engineer John Ericsson invented the hot air engine, the steam condenser, and revolutionized ship propeller design, incorporating the landmark device into his design for the Civil War ironclad Monitor. Ericsson writes to an unknown correspondent about his hot air engine. In part: "The application of the vacuum cylinder for the back stroke, Tyler thinks removes the last objection. Put our friend down as one who will make the patent valuable. As soon as Mr. T returns from the South he will knock at the door of the patenter for a License." Letter has been tipped to a heavier backing sheet together with a trimmed portion of another letter. Lightly age toned; generally fine.Auction Info
