Utilizing his exceptional education and continuing the public service of his distinguished parents, planter-lawyer-politician-soldier-philanthropist Pinckney became one of the outstanding men of his time. During the Revolution, he espoused the Whig cause; bore arms during the War for Independence; and ranked among the leaders at the Constitutional Convention. Besides serving in the State legislature, he rendered diplomatic service to the Nation, nad was once the Vice-Presidential and twice the Presidential candidate of the Federalists.
The eldest son of a politically prominent planter and a remarkable mother who introduced and promoted indigo culture in South Carolina, Charles Cotesworth [Pinckney] was born in 1746 at Charleston. Only 7 years later, he accompanied his father, who had been appointed colonia agent for South Carolina, to England. As a result, the youth enjoyed a European education.
Pinckney received tutoring in London, attended several preparatory schools, and went on to Christ Church College, Oxford, where he heard the lectures of the legal authority Sir William Blackstone and graduated in 1764. Pinckney next pursued legal training at London's Middle Temple and was accepted for admission into the English bar in 1769. He then spent part of a year touring Europe and studying chemistyr, military science, and botany under leading authorities.
