During this time, entertainments were varied; opera and ballet were presented, but not exclusively. Kemble engaged a variety of acts, including the child performer "Master Betty"; the great clown Joseph Grimaldi made his name at Covent Garden. Many famous actors of the day appeared at the theatre, including the tragediennes Sarah Siddons and Eliza O'Neill, the Shakespearean actors William Charles Macready, Edmund Kean and his son Charles. On 25 March 1833 Edmund Kean collapsed on stage while playing Othello, and died two months later.
