Martyn, Henry' (1781-1812), missionary, was the son of a Cornish miner. He was Senior Wrangler at Cambridge, and Smith's prizeman in 1801, and was for a time curate under Charles Simeon, but in 1805 sailed for India as a military chaplain. He died at Tokat, in Asia Minor, when on his way from Persia to Europe. His life had been a weary one, owing to disappointment in love and habitual ill-health. He translated the New Testament into Persian and Hindustani, and the Psalms also into Persian.
