Eugene Bourdon was a maker of repute. Whilst the design of the aneroid barometer was being developed by a rival French engineer Vidie, Bourdon patented this type of barometer guage in 1849 and it was initially widely used.
According to Edwin Banfield’s book, Barometers Aneroid and Barograph, Richard may have been working with Bourdon before he went into partnership with Richard Frères in 1858, a partnership which went on to become a prolific producer of carriage clocks over the next few decades.
Whilst many example of Bourdon’s barometers remain today, only 500 of these combination clock barometers were ever produced, making them a much rarer find.
