There were those concerned that the theatre was failing in its role as one of the very few permitted to show legitimate drama. Management of the theatre after it reopened in 1813 fell to Samuel James Arnold, overseen by an amateur board of directors and a subcommittee focusing on the theatre as a centre for national culture. (Lord Byron was briefly on this subcommittee, from June 1815 until leaving England in April 1816.) Actor Edmund Kean was the on-stage highlight; like Macklin before him, he made his reputation as Shylock, premiering in the role in 1814. Kean remained until 1820 through praise and notorious disputes with local playwrights such as Charles Bucke.
