George Shillibeer (1797-1861) introduced omnibuses (which he had seen in Paris) to Britain. On 4 July 1829 he started a three-horse vehicle along the new road from Paddington Green to the Bank via Islington. His omnibuses carried twenty passengers all inside, charging high middle-class fares - a shilling all the way; six pence half way. [Ref.
