in the commercial heart of the city (rather than the ancient but much smaller collegiate enclave of Old Aberdeen), was quite different in nature and outlook. For example, it was more integrated into the life of the city, such as allowing students to live outwith the college. The two rival colleges often clashed, sometimes in court, but also in brawls between students on the streets of Aberdeen. Duncan Liddell endowed the first chair in mathematics at Marischal College in 1613, but the first professor was not appointed until 1626.

During this time, both colleges made notable intellectual contributions to the Scottish Enlightenment. Both colleges supported the Jacobite rebellion and following the defeat of the 1715 rising were largely purged by the authorities of their academics and officials.

Following the civil conflicts of the Wars of the Three Kingdoms, a more complete unification was attempted following the ratification of Parliament by Oliver Cromwell during the interregnum in 1654. This united university survived until the Restoration whereby all laws made during this period were rescinded by Charles II and the two colleges reverted to independent status. Charles I is still recognised as one of the university's founders, due to his part in creating the Caroline University and his benevolence towards King's College.
The Aberdeen Philosophical Society (known locally as the Wise Club) was created by Thomas Reid, George Campbell, David Skene, John Gregory, John Stewart, and Robert Traill, and held its first meeting in the Old Red Lion Inn on 12 January 1758. From its inception, the society was an intimate, private body whose …
