Solomon Davies Warfield (September 4, 1859 – October 24, 1927) was an American railroad executive and banker.

[1][2] Warfield's father was a prominent grain merchant and director of the Baltimore and Ohio Railroad.

During World War II, the President Warfield was acquired by the U. S. government and transferred to Great Britain in 1942 under the Lend-Lease program to serve as a troop transport.

Purchased secretly in 1946 by the Jewish nationalist organization Haganah and renamed Exodus 1947, the ship was briefly in the world spotlight as one of several vessels illegally attempting to carry Jewish refugees to British-controlled Palestine.

This unsuccessful incident was later the subject of the 1958 novel Exodus by Baltimorean Leon Uris, (1924-2003) and the motion picture based upon it, released in 1960.
