John Frederick Newman (fl. 1816-1860) was one of the leading barometer makers of the 19th Century whose meterorological station barometers were installed throughout the British Empire. Operating from 122 Regent Street between 1827 and 1860, he made the standard and portable barometers for the Ross Antarctic expedition (N.
