Maximilian Joseph Johannes Eduard Schuler (5 February 1882 in Zweibrücken – 30 July 1972) was a German engineer and is best known for discovering the principle known as Schuler tuning which is fundamental to the operation of a gyrocompass or inertial guidance system that will be operated near the surface of the earth.
Schuler´s cousin Hermann Anschütz-Kaempfe founded a firm near Kiel, Germany, to manufacture navigational devices using gyroscopes in 1905, and Schuler joined the firm in 1906. For many years they struggled with the problem of maintaining a vertical reference as a craft moved around on the surface of the earth.
