Royal Observatory, Edinburgh
The University of Edinburgh in 1785 and by Royal Warrant of George III created the Regius Chair of Astronomy and appointed Robert Blair first Regius Professor of Astronomy. After his death in 1828 the position remained vacant until 1834. In 1811 private citizens had founded the Astronomical Institution of Edinburgh with John Playfair – professor of natural philosophy – as its president. The Institution acquired grounds on Calton Hill to build an observatory, which was designed by John's nephew William Henry Playfair; it remains to this day as the Playfair building of the City Observatory.
