John Allan Broun FRS (21 September 1817 – 22 November 1879) 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. ==Early years== Broun was born in Dumfries and educated at Edinburgh University and was later the director of the magnetic observatory at Makerstoun, in Scotland, from 1842 to 1849. This observatory had been founded by Sir Thomas Brisbane. The observations Broun made at Makerstoun were published in the Transactions of the Royal Society of Edinburgh.
