Johannes Zimmermann (missionary)

Johannes Zimmermann (2 March 1825 – 13 December 1876) was a missionary, clergyman, translator, philologist and ethnolinguist of the Basel Evangelical Missionary Society of Switzerland, who translated the entire Bible into the Ga language of the Ga-Dangme people of southeastern Ghana and wrote a Ga dictionary and grammar book. Mostly an oral language before the mid-nineteenth century, the Ga language assumed a written form as a result of his literary work. Zimmerman's work built upon the single introductory grammatical treatise written by the Euro-African Moravian missionary and educator, Christian Jacob Protten, in the Ga and Fante languages, and published a century earlier in Copenhagen, in 1764.
