Ernest Frank Guelph Cox (1883–1959) was an English engineer, with knowledge in electrical and mechanical engineering, which he notably deployed in marine salvage. Between 1924 and 1931 his Cox &amp; Danks Shipbreaking Co. successfully raised 35 ships of the German Imperial Navy High Seas Fleet that had been scuttled at Gutter Sound, Scapa Flow, in 1919. A tough but caring employer, after a series of fatalities and accidents to his employees, Cox sold his marine salvaging business to the Alloa Shipbreaking Company in 1932. He remained a consultant to the British Admiralty throughout his remaining career, and retired in the early 1950s after selling his profitable scrap metal business to Metal Industries Group.
