The brougham (pronounced 'brohm' or 'broom') was invented for jurist Henry Brougham, or became very fashionable by his use of it. It was a four-wheeled horse-drawn carriage that could seat two within its enclosed body and sometimes had a pair of fold-away seats in the front corners.
It had a seat in front for the driver and a passenger. It also had a glazed front window, so that the occupants could see forward. It was a light vehicle, and the forewheels were capable of turning sharply.
