John Patrick Crichton-Stuart, 3rd Marquess of Bute (1847-1900), funded the construction of the great hall in Gilmorehill that bears his name.
The University buildings remained incomplete in 1877, seven years after the move from High Street, and Bute and Charles Randolph committed funds to enable the completion of two great building schemes - the construction of what became known as the Bute and Randolph Halls.
Crichton-Stuart was born on the Isle of Bute, the son of the second Marquess. He inherited a vast family fortune that enabled him to pursue a number of scholarly, spiritual, political and architectural interests during his life. His family built and owned Cardiff Docks, and Bute served twice as as that city's mayor. His private life and beliefs were the subject of some controversy: Bute was born a Protestant but converted to Catholicism in 1868, and although he was a Conservative he advocated Home Rule for Scotland.
