John Allan Broun

John Allan Broun FRS was a Scottish scientist with interests in magnetism, particularly of the earth, and meteorology. Broun studied in Edinburgh University and worked at the observatory in Makerstoun from 1842 to 1849 before moving to India to work in the Kingdom of Travancore. He continued his studies on geo-magnetism in India and was involved in setting up observatories there apart from managing the Napier Museum in Trivandrum. One of the fundamental discoveries he made was that the Earth loses or gains magnetic intensity not locally, but as a whole. He also found that solar activity causes magnetic disturbances.
