John Serson

John Serson (died 1744) was an English sea captain best known for his invention of a "".^[1] This was an early form of artificial horizon designed for marine navigation, consisting of a mirror, attached to a spinning top, that attempted to remain in a horizontal plane despite the movement of the ship. This device can be seen as a precursor to the gyroscope used in modern inertial navigation, although it was not itself a gyroscope.^[2]

Serson was lost at sea on HMS Victory in 1744.^[3]
