Edinburgh Napier University is a university in Edinburgh, Scotland. It is one of Scotland's largest universities with nearly 18,000 students. Edinburgh Napier University was opened as Napier Technical College in 1964, taking its name from John Napier, the inventor of logarithms, who was born at Merchiston Castle — the site of the University's Merchiston campus. In 1966, it was renamed Napier College of Science and Technology. Since 1971, it has offered degree-level education. Three years later, it merged with the Sighthill-based Edinburgh College of Commerce to form Napier College of Commerce and Technology, which became a Central Institution in 1985. The college was renamed Napier Polytechnic in 1986 and in the same year acquired the former Hydropathic hospital buildings at Craiglockhart. It gained full university status in June 1992 as Napier University. In 1994, Napier University acquired its Craighouse campus. In 1996, the university gained a new Faculty of Health Studies through a merger between the Scottish Borders College of Nursing and Lothian College of Health Studies.
