Thorsten Nordenfelt (1842-1920), was a Swedish inventor and industrialist. Nordenfelt was born in Örby outside Kinna, Sweden, the son of a colonel. The surname was and is often spelt Nordenfeldt, though Thorsten and his brothers always spelt it Nordenfelt, and the 1881 Census shows it as Nordenfelt. The family home in that year was Leinster Lodge on the Uxbridge Road, Paddington in west London. Thorsten worked for a Swedish company in London from 1862 to 1866 and migrated to England in 1867 when he married Emma Stansfeld Grundy. In 1903 he returned to Sweden and retired.
