Copeland's method was devised by Ramon Llull in his 1299 treatise "Ars Electionis" and discussed by Nicholas of Cusa in the fifteenth century and by the Marquis de Condorcet in the eighteenth (who drew attention to the related criterion). However, it is frequently named after Arthur Herbert Copeland who advocated it independently in a 1951 lecture.
