John Eliot was a 17th-century Puritan missionary and linguist who lived in the Massachusetts Bay Colony. Born in Hertfordshire, England, he emigrated to Boston in 1631 and served as a minister in Roxbury for several decades. He is most famous for his extensive linguistic work, specifically translating the Bible into the Massachusett language. This monumental achievement, completed in 1660, represented the first full Bible printed in the Western hemisphere. Beyond his missionary efforts, he was an educator who established the Roxbury Latin School in 1645.
