The founder and first Chief Burgess of Bangor was Robert M. Jones, an emigree from Bangor, Wales. He was the prime mover in the establishment of the slate industry in Northampton County. A life-sized statue of him, dedicated on September 24, 1914, remains in the town center. In the official program for the unveiling it states "... Mr. Jones in his prime had many charming qualities, chief among which was his constant optimistic disposition."
