John Horden was a 19th-century Anglican priest and the first Bishop of Moosonee in Canada. Born in Exeter, England, in 1828, he traveled to the Hudson's Bay Territory in 1851 to serve as a schoolmaster and catechist. Over a missionary career spanning more than forty years, he worked extensively with Cree and Inuit communities. He was a dedicated translator who produced various religious texts in indigenous languages, facilitating spiritual life for his parishioners through both oral services and printed materials.
