Admiral Gago Coutinho was a pilot for the Portuguese Navy in the 1920s. He is famous for his 1922 flight across the South Atlantic with fellow navigator, Commander Sacadura Cabral, the first flight to use celestial navigation for an oceanic crossing. Admiral Coutinho designed the instrument and developed the methods for the flight. He worked with C. Plath, a German manufacturer of nautical instruments, to improve the sextant over the next 15 years.
