Lot Essay
Brunel's "Great Britain" was the first iron steam ship built for and employed on the Atlantic. The initial success of the "Great Western," launched on July 19, 1837, inevitably led to plans for a still larger vessel that would have to be of iron. Originally called the "Mammoth," she too was built at Bristol by Paterson and floated out on July 19, 1843. With a displacement of 3618 tons, she was four times larger than other iron vessels, and the first large ship to be driven by a screw.
