Hill and his brothers had taken over the management of their father's school in Birmingham in 1819, which opened a branch at Bruce Castle in 1827, with Rowland Hill as Headmaster. The school was run along radical lines inspired by Hill's friends Thomas Paine, Richard Price and Joseph Priestley; all teaching was on the principle that the teacher's role is to instill the desire to learn, not to impart facts, corporal punishment was abolished and alleged transgressions were tried by a court of pupils, while the school taught a radical (for the time) curriculum including foreign languages, science and engineering. Among other pupils, the school taught the sons of many London-based diplomats, particularly from the newly independent nations of South America, and the sons of computing pioneer Charles Babbage.
