born Aug. 24, 1886, Philadelphia, Pa., U.S.
died Sept. 6, 1967, New York, N.Y.
U.S. naval architect.
He initially studied law but turned to naval architecture, studying for a year in seclusion, and with his brother Frederick H. Gibbs designed a transatlantic liner. During World War I they designed ships for the U.S. government, and after the war they were commissioned to recondition the Leviathan . Gibbs's design for the Malolo (1927), with its numerous watertight compartments and other safety features, became an industry standard. In 1940 he designed a cargo ship suitable for mass production; using prefabrication techniques, he reduced production time from as long as four years to as little as four days, an innovation of enormous value in World War II. His passenger liner United States (1952) set speed records in transatlantic service.
