1777568181Code 8427 Pocket CompassKeuffel & Esser Co., New York, pocket compass, used by U.S. Army officers during World War I. Chrome-plated brass, shaped like an onion watch. The compass features a snap-lock lid with a release button inside the ring. Good condition, fully functional. Dimensions: 4.5 x 1.3 cm – 1.8 x 0.5 in.

Keuffel & Esser Co. was a company that manufactured drafting instruments, founded in 1867 by W.J.D. Keuffel and H. Esser. The firm began selling drafting and design instruments in New York and then began selling surveying instruments in 1876. In 1889, the company moved to new facilities in New Jersey, and over the next ten years began marketing a new line of surveying instruments based on the work of John Paoli, an Italian immigrant. Around the same time, it also began manufacturing sextants, in agreement with the U.S. Navy. In the 1920s, the company began manufacturing slide rules; during World War II, it produced fire-prevention instruments for the U.S. government and won three Army-Navy E Awards for manufacturing excellence.

The Greeks and Romans were still unaware of the possibility of exploiting magnetic fields for orientation, while it seems that this possibility was already somewhat known to the Chinese: around 2600 BC, Emperor Hoang-Ti managed to defeat Prince Tchi-Yeou in battle thanks to a "magic" chariot, the See-Nan (chariot indicating south). Thanks to this device, the emperor identified the enemy's escape route, even though the enemy had hidden it with a blanket of smoke. Fixed to the chariot was a wooden human-shaped figure that rotated on itself and, with its arm outstretched, always pointed south (indicating south obviously also indicated north, but south was considered the most important cardinal point by the Chinese). The Chinese also used their discoveries relating to magnetic fields as a form of entertainment and spectacle: they threw magnetized arrows like dice, and these aligned in a south-north direction as if by magic, which greatly impressed and amazed the spectators.
