Fellows of The Royal Society have been interested in weather from the earliest years of the Society. When John Locke was in Montpellier in 1676 he made many observations of the weather, which are in his unpublished Journal. Edmond Halley collected observations of winds worldwide from sea captains and published a chart of the trade winds in Philosophical Transactions. Robert Hooke devised a barometer for use at sea. Present Fellows are deeply involved with questions of change of climate. Our Archivist assembled a number of items from the Library for the New Frontiers in Science Soirées last year in an exhibition entitled ‘From Hooke to Houghton. Meteorology and The Royal Society’, which showed the continuing study by Fellows of weather and climate over three centuries. We reproduce some of the pictures here as a sample of those studies.
