Stephen Groombridge

Stephen Groombridge FRS (7 January 1755 – 30 March 1832) was a British merchant and astronomer.

He succeeded when about 21 to the business in West Smithfield of a linen draper named Greenland, to whom he had been apprenticed.

He spent ten years making observations on the Groombridge Transit Circle and another ten years doing reductions of the data (correcting for refraction, instrument error and clock error).

His Catalogue of Circumpolar Stars was published posthumously in 1838 with the help of fellow astronomer George Biddell Airy and others.

In 1842, one of the stars in his catalogue, Groombridge 1830, was discovered by Friedrich Wilhelm Argelander to have a very high proper motion.
