Charles Nelson Tripp
Charles Tripp and his brother, Henry Tripp, operated the first bitumen/asphalt business in Enniskillen Township, Lambton County, Ontario, in the early 1850s. The business failed due to the high transportation costs, production difficulties, and lack of capital. Some of his lands were purchased by James Miller Williams who then developed North America's first commercial oil well.
