Shipwrecked Mariners’ Society Marine Barometers in Unusual Cases
The Shipwrecked Fishermen and Mariners’ Royal Benevolent Society, better known as the Shipwrecked Mariners’ Society, was established by John Rye in February 1839 as a result of the tragic loss of a fleet of fishing boats on the north Devon coast in October 1838.

On This Day – 8th August 1908 – Wilbur Wright
On this day in 1908, Wilbur Wright publicly demonstrated a Wright aircraft for the first time in Europe at the Hunaudières racecourse at Le Mans, southwest of Paris. The airplane was an improved version of the brothers’ experimental designs flown in 1903-1905. Wilbur’s flights at Le Mans confirmed without doubt the Wrights’ claims to have developed a successful airplane and...

The Quest for Greater Resolution in Aneroid Barometers I
As marvellous an invention as the aneroid barometer was, it had many shortcomings, most of which were approached by various instrument makers over the 100 years or so of production. Resolution, perhaps expressed as the reading to the highest number of decimal places, was an illusive goal. The problem relates to the expansion and contraction of the cell over a...

Harrison’s Chronometer and the Determination of Longitude
The Science Museum recently posted a very interesting blog about the story behind John Harrison and his portrait at the Royal Observatory. In its own way, the invention of the aneroid barometer by Lucien Vidi and its determination of altitude was as significant an invention in the 19th century as Harrison’s was in the 18th. https://blog.sciencemuseum.org.uk/portrait-mr-harrison-timekeepers/
