Harvard Theatre Collection. Their success on the London stage allowed the Grimaldis to enjoy an affluent lifestyle in contrast to other working-class families living in Clare Market and Holborn. By the age of six, Grimaldi was considered a prominent stage performer by the press, with one critic from the Gazetteer commenting that "the infant son of Grimaldi performs in an astonishing manner". One evening, Grimaldi was playing the part of a monkey and was led onto the stage by his father, who had attached a chain to Grimaldi's waist. Giuseppe swung his young son around his head "with the utmost velocity", when the chain snapped, causing young Grimaldi to land in the orchestra pit. From 1789 Grimaldi would appear alongside his siblings in an act entitled "The Three Young Grimaldis". Grimaldi's father suffered ill health for many years and died of dropsy in 1788. As a result, at age 9, Grimaldi became the family's principal breadwinner. Sheridan paid him an above-average wage of £1 a week at Drury Lane, and allowed his mother to work at Drury Lane as a dancer. However, the proprietors of Sadler's Wells were less supportive, cutting Grimaldi's pay from 15 shillings to 3 shillings a week, at which level it remained for the next three years. The loss of Giuseppe's income and Joseph's reduced summertime earnings meant the Grimaldis could no longer afford to keep the house in Holborn. They moved to the slum district of St. Giles, where they took lodgings with a furrier in Great Wild Street. Grimaldi's brother, John Baptiste, illegally signed on as a cabin boy aboard a frigate in 1788, when he was nine, using a false identity. Grimaldi saw him only once more in his life. John Philip Kemble took over the producer's (director's) duties at Drury Lane later in 1788 when Sheridan was promoted to chief treasurer. Sheridan often employed Grimaldi in minor roles in Kemble's productions and continued to allow him to work concurrently at Sadler's Wells. Grimaldi took an interest in the design and construction of stage scenery and would often help to design sets. His stage performances over the next two years did not garner him the kind of success he had experienced under the management of his father, and the role of pre-eminent Clown in London productions soon fell to Jean-Baptiste Dubois, a versatile French acrobat, horseman, singer and strongman, with a formidable repertoire
