s 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. In 1923 Schuler published his discovery that if the gyrocompass was tuned to have an 84.4 minute period of oscillation (the ''Schuler period'') then it would resist errors due to sideways acceleration of the ship or aircraft in which it was installed. Later, Schuler served as a professor of dynamics at the
