The Wall Street millionaire Alfred Loomis was an amateur physicist who made significant contributions to scientific research. In 1928 he purchased three identical clocks, the most accurate available at that time. Loomis set up the clocks in a triangular orientation to one another, to break the gravitationally induced synchronic action among their pendulums, and by analyzing their minute variations, verified a theoretically predicted tidal effect of the Moon on clocks. These results later contributed to the development of LORAN (Long-Range Navigation), which triangulates the positions of ships and aircraft by comparing the difference in arrival times of signals coming from multiple radio beacons at various groundbased locations, a calculation that depends on accurate timekeeping
