The "cut" allowed for settlement of an area of the city previously uninhabitable because of the grade of the land. The city also expanded during his time as mayor with the annexation of the Northern Liberties Borough.^[4]

He worked as a melter and refiner at the Philadelphia Mint from 1840^[5] to 1847.^[2]
