Montgomery Bell (January 3, 1769, Chester County, Pennsylvania – April 1, 1855, Dickson County, Tennessee) was a manufacturing entrepreneur who was crucial to the economic development of early Middle Tennessee. He was known as the "Iron Master of the Harpeth" and the "Iron Master of Middle Tennessee". Today he is remembered mostly for the founding of one of the largest non-sectarian all-boys private secondary schools in the United States, which bears his name.
