This miniature after an original painting by Sir William Beechey (1753-1839) now in the Dulwich Picture Gallery represents John Philip Kemble (1757-1873), the eleventh son of the strolling actors Roger and Sarah Kemble and brother of the famous actors Sarah Siddons, Charles Kemble and Stephen Kemble. In a time before photography, many affluent people had miniature portraits painted. They were light and portable and could be given to friends or relatives, often in silk-lined leather carrying cases made specially for them. A smilar engraving by Piercy Roberts was published in The Thespian Dictionary, 1802, after Sir William Beechey's portrait of Kemble.

Born in 1757, John Philip Kemble was one of the twelve children of the strolling actor-manager Roger Kemble, all of whom took to the stage. In preparation for a career in the Church, he was educated at a Jesuit college in Douai in northern France from 1771 until 1775, but on his return embarked upon a stage career, possibly influenced by the success of his elder sister, the great Sarah Siddons.

J. P. Kemble went on to become a stately, formal actor best-known for his interpretation of heavily dramatic roles including Hamlet, Brutus, Cato, Rolla and Coriolanus. It is said that he was never suited for comedy and that even in his most convivial moods was 'solemn and funereal'. He managed both the Theatre Royal, Drury Lane, and Covent Garden where he caused the Old Price Riots by raising the price of admission to pay for rebuilding after the fire of 1808. He made several important reforms at Drury Lane Theatre, both in management and in costumes and scenery, and controversially introduced spectacular shows there featuring live animals and aquatic effects. His years of management were not considered a financial success. He died in Lausanne in 1823.
