In a long stream of historical allusions, Richard Brinsley Sheridan (1751–1816) is the first personage Verne uses to add substance and believability to his fanciful tale. Sheridan was the owner of London's Theatre Royal in Drury Lane. A poet and playwright noted for The School for Scandal and others, he also had a political career as a Whig MP, a Member of Parliament, House of Commons, for Stafford, England. He is buried in Poet's Corner at Westminster Abbey.
