1911 Encyclopædia Britannica/Brougham

BROUGHAM, a four-wheeled closed carriage, seating two or more persons, and drawn by a single horse or pair, or propelled by motor. The modern “brougham” has developed and taken its name from the “odd little kind of garden-chair” described by Thomas Moore, which the first Lord Brougham had made by a coachmaker to his own design.
