Executive summary: A Catalogue of Circumpolar Stars

Self-taught astronomer Stephen Groombridge was for many years a merchant and importer, specializing in trade with the West Indies, but he was always fascinated by the heavens. In 1806 he hired noted instrument-maker Edward Troughton to construct one of the first modern transit circles, and he then spent ten years making thousands of observations with it. Intending to create a thorough catalogue of known stars within 50 of the North Pole, in 1815 he retired from his business, and spent the next decade continuing his observations while double-checking his data, making corrections for refraction, instrument error and clock error. When a stroke left Groombridge paralyzed and unable to complete his work, the catalogue was finished by friends and fellow scientists, and published after Groombridge's death. He was one of the founding members of the Astronomical Society of London, now known as the Royal Astronomical Society, and he is the namesake of one of the stars he discovered, the sub-dwarf Groombridge 1830 in the Ursa Major constellation.
