History

Short's Observatory

In the early 18th century, the Edinburgh instrument maker Thomas Short leased some land on Calton Hill to display his instruments to the public. As his lease stipulated female relatives of Thomas could not inherit the building and its contents, his wife and children did not inherit it when he died in 1788. In 1827, Maria Theresa Short returned to

. She exhibited many scientific instruments and kept her Observatory open till 9pm each evening. After this very popular observatory was pulled down by authorities against her protests in 1851, she moved to Castlehill. In 1852, she bought the Laird of Cockpen’s townhouse, adding two storeys to create ''Short's Observatory, Museum of Science and Art'', in existence from 1853 to 1892. The tenement is thought to be the original mansion of the Ramsays of Dalhousie (the "Lairds of Cockpen"), turned into small flats in the 18th century. The main attraction in "Short's Observatory" was the ''camera obscura'' occupying the topmost room. Her husband, Robert Henderson, continued to run the attraction after Maria died in 1869.
