Scottish physicist, meteorologist and Nobel Laureate Charles Thomson Rees Wilson is noted for inventing the cloud chamber particle detector, also referred to as Wilson cloud chamber, used for visualizing the passage of ionizing radiation. It played a significant role in the area of experimental particle physics between the 1920s and 1950s.
Scottish meteorologist and geophysicist Balfour Stewart is best remembered for his research on radiant energy and terrestrial magnetism. Initially a trader, he later joined the Kew Observatory as an assistant and eventually became its director. The Unseen Universe remains one of his best-known written works.
British meteorologist and physicist John Aitken is best remembered for his research on the microscopic particles now known as the Aitken nuclei and their role in the condensation of water vapor. However, health issues kept him confined to his home laboratory and prevented him from taking up significant positions.
Thomas Stewart Traill had donned many hats. Initially a practicing physician, he was also interested in zoology and helped John James Audubon publish The Birds of America.
