Explanation:

Pinckney graduated as a lawyer in 1779. During the American Revolutionary War he was forced to be a British prisoner of war. From 1784 to 1787 he was a member of the Confederate Congress, where he strongly advocated the adoption of a new constitution. At the 1787 Constitutional Convention, Pinckney, representing South Carolina, presented a detailed constitutional plan known as the Pinckney Plan. It has not preserved its original drafts, but has been known to contain many points that also led to the final Constitution of the United States.
