POST, Christian Frederick, missionary, born in Polish Prussia in 1710; died in Germantown, Pennsylvania, 29 April, 1785. He came to Pennsylvania in 1742, and between 1743 and 1749 was a missionary to the Moravian Indians in New York and Connecticut. He returned to Europe in 1751, and thence was sent to Labrador, but afterward he came again to Pennsylvania, and was again employed in the Indian missions. In 1758 he undertook an embassy in behalf of the province to the Delawares and Shawnees in Ohio. He established an independent mission in Ohio in 1761, where he was joined in 1762 by John Heckewelder; but the Pontiac war forced them to abandon the project. In January, 1764, he sailed for the Mosquito coast, where he labored two years, and he made a second visit there in 1767. He afterward united with the Protestant Episcopal church.
