First published in 1960, this book details the life of Ludovic Zamenhof, the creator of Esperanto. Boulton’s work portrays Zamenhof as a figurehead for peace, his life and work remaining morally, intellectually, and psychologically interesting over time. The book uncovers Zamenhof’s early years, where he, at the age of fifteen, conceived the idea of creating a new language, spurred by the notion of bringing humanity together and achieving peace through the invention of a single language for mankind. This book will be of interest to both historians and linguists alike, as Boulton’s book gives a revealing view of Europe in the late 19th and early 20th centuries, a time when Esperanto spread worldwide.
