Heath & Company was founded by George Heath in London in 1845. Primarily a manufacturer of thermometers and navigational instruments, they used the Hezzanith trade mark on many of their instruments. Around 1937 they were incorporated with W F Stanley & Co Ltd. They were still in business in the 1960s.
