Joseph Grimaldi was an English actor, comedian and dancer, who became the most popular English entertainer of the Regency era. In the early 1800s, he expanded the role of Clown in the harlequinade that formed part of British pantomimes, notably at the Theatre Royal, Drury Lane and the Sadler's Wells and Covent Garden theatres. He became so dominant on the London comic stage that harlequinade clowns became known as "Joey", and both the nickname and Grimaldi's whiteface make-up design were, and still are, used by other types of clowns. Grimaldi originated catchphrases such as "Here we are again!", which continue to feature in modern pantomimes. Born in London to an entertainer father, Grimaldi began to perform as a child, making his stage debut at Drury Lane in 1780. He became successful at the Sadler's Wells Theatre the following year; his first major role was as Little Clown in the pantomime The Triumph of Mirth; or, Harlequin's Wedding in 1781, in which he starred alongside his father. After a brief schooling, he appeared in various low-budget productions and became a sought-after child performer. He took leading parts in Valentine and Orson and The Talisman; or, Harlequin Made Happy, the latter of which brought him wider recognition.
