Max Schuler

…possible through the efforts of Max Schuler, who developed the principles on which a practical shipborne gyrocompass depends. This compass was a marvel of mechanical ingenuity. In 1911 Elmer Sperry in the United States produced a gyrocompass that was easier to manufacture. In England, Sidney George Brown, working with John…

…the Sperry, was developed by Schuler. It consists of applying an antipendulous torque caused by the restricted flow of a viscous fluid responding to the tilt of the gyroscopic element. Viscosity and direction of flow through the constriction are combined so that the torque is applied in the proper phase…
