For the past five years, Esther Schor, Behrman Professor in the Humanities Council and a professor of English, has been conversing with Esperantists (in Esperanto) around the world to research her new book, Bridge of Words: Esperanto and the Dream of a Universal Language (Metropolitan Books/Henry Holt, 2016). The book is a full history of the constructed language — from its linguistic mechanics to its core ideals that have survived into the digital age.
