Captain F. Creagh-Osborne (1867-1943) was an inventor and Superintendent of Compasses with the British Admiralty. He joined the Royal Navy in 1881 and went on to be a pioneer in the field of aerial navigation. He introduced numerous innovations in compass design, producing models for use on land and in aircraft. Many of his designs were put into production by H. Hughes & Son Ltd and the Sperry Gyroscope Company.
