Heriot-Watt was established as the School of Arts of Edinburgh by Scottish businessman Leonard Horner on 16 October 1821. Having been inspired by Anderson's College in Glasgow, Horner established the School to provide practical knowledge of science and technology to Edinburgh's working men. The institution was initially of modest size, giving lectures two nights a week in rented rooms and boasting a small library of around 500 technical works. It was also oversubscribed, with admissions soon closing despite the cost of 15 shillings for a year's access to lectures and the library.
