From 1902 to the mid-1920s, this industrial site was home to the Standard Materials Co. and the Gyro Moto Co., where inventor Emile Berliner and his son-in-law, Joseph Sanders, developed and manufactured products such as the flat disc gramophone and the gyro engine, an early component of the modern helicopter.
