Daniel Clark Sr.

Daniel Clark Sr. (1732–July 16, 1800) was an 18th-century Irish-American merchant and land owner in colonial Pennsylvania and the lower Mississippi River valley. Clark dealt in groceries, tobacco, and slaves. His nephew, Daniel Clark, left Ireland to join him in business and eventually became an important political figure of Louisiana at the turn of the 19th century. Clark had a business partnership with James Wilkinson, who was both an American general and an employee of the Spanish government. The now-extinct Natchez District town of Clarksville was developed by and named for Clark.
