This barometer was made by Daniel Quare, a leading London clockmaker. Quare obtained a patent for a barometer design in 1695. This claimed that the barometer could be inverted without either spilling the mercury or allowing air to get into the tube. William Derham, clergyman and natural philosopher, published an article in the Philosophical Transactions of the Royal Society describing using Quare’s barometer in experiments concerning air pressure at the Monument in 1697.
