(1767–1836) English astronomer. He was appointed the sixth Astronomer Royal in 1811. Pond installed new instruments at Greenwich Observatory, having previously revealed errors in star positions caused by warping of the observatory's ageing equipment, and in 1833 produced a star catalogue of unprecedented accuracy. That same year he introduced the first public time signal by dropping a time ball each day at 1 p.m.
