Sir Humphrey Chetham bequeathed the music college to the World in his will - it was then part of the cathedral, and the main gun-powder store in the civil war years - the siege of manchester was mainly caused when the Earl Od Derby tried to collect the powder supplies, which were in fact his - Parliament confiscated the supplies illegally.
Chetham was a leading financier and kept the accounts for all parliament expenditure in the north west - he just got out of Bolton before the massacre there - the college he left is now the music college
