Eliza Lucas Pinckney (December 28, 1722–1793) changed agriculture in colonial South Carolina, where she developed indigo as one of its most important cash crops. Its cultivation and processing as dye produced one-third the total value of the colony`s exports before the Revolutionary War. Manager of three plantations at age 16, Pinckney had a major impact on the economy. She was the first woman to be inducted into South Carolina`s Business Hall of Fame.
