About the author

J. C. O'Connor, or John Charles O'Connor, was born in 1853 and died in 1928. He is chiefly remembered through his Esperanto-related books, including Esperanto: The Universal Language, a student textbook, and the English-Esperanto Dictionary, prepared with C. F. Hayes.

The record of his life online is much thinner than the record of his books, so it is safest to describe him as an early contributor to Esperanto publishing for English readers rather than to claim many personal details. His work appeared at a time when Esperanto was being introduced to a wider international audience, and his books were designed to be practical tools for study, conversation, and reference.

That makes O'Connor an interesting figure for modern readers: not just a name from the past, but part of the effort to turn Esperanto from an idea into something ordinary people could actually learn and use.
