Francis Mason (1799-1874), American missionary, was born in York, England. His grandfather, also Francis Mason, was the founder of the Baptist Society in York, and his father, a shoemaker by trade, was a Baptist lay preacher there. After working with his father as a shoemaker for several years, he emigrated in 1818 to the United States, and in Massachusetts was licensed to preach as a Baptist in 1827. In 1830 he was sent by the American Baptist Missionary Union to labor among the Karens in Burma. Besides conducting a training college for native preachers and teachers at Tavoy, he translated the Bible into the two principal dialects of the Karens, the Sgaw and the Pwo, and Matthew, Genesis, and the Psalms into the Bghai dialect. He also published A Pali Grammar on the Basis of Kachchaya, with Chrestomathy and Vocabulary (1868). In 1852 he published a book of great value on the fauna and flora of British Burma, of which an improved edition appeared in 1860 under the title Burmah: Its People and Natural Productions.
