About the author
John Charles O'Connor was a writer and teacher of Esperanto whose books focused on making the language approachable for English-speaking learners. Records for his publications identify him as J. C. O'Connor (1853–1928), and his best-known work, Esperanto (The Universal Language), was issued by Fleming H. Revell in revised form in 1907.
His books were strongly practical in spirit. Esperanto (The Universal Language) was presented as a student's textbook with grammar, exercises, conversations, commercial letters, and vocabularies, while English-Esperanto Dictionary, prepared with C. F. Hayes, shows his interest in giving learners usable reference tools rather than abstract theory.
Little biographical detail about his personal life was easy to confirm from reliable online sources, so the surviving picture is mainly that of a committed popularizer of Esperanto. Even so, his published work makes his purpose clear: to help readers use a shared language simply, confidently, and in everyday life.
