Rebecca Pennock Lukens (1794-1854) owned and managed the iron and steel mill known as Lukens Steel Company from 1825 until 1849. Her parents Issac Pennock and Martha Webb Pennock were Quakers and her father started an iron works business.

She married Charles Llyod Lukens (1786-1825) in 1813. They had a son and four daughters who survived infancy: Charles Edward (1819-1824), Martha (1814-1892), Elizabeth (1817-1832), Isabella (1822-1889), and Charlesanna (1825-1849). Charles L. Lukens was a physician and left his practice to work with her father at the iron works.

Within the span of a year her father, son and husband died leaving the mill in debt. She began running the mill and later remodeled it making improvements and building up the store and warehouse. Her daughter's husbands Abraham Gibbons and Charles Huston joined the firm, in 1842 and 1849 respectively. She stepped down in 1849. In 1890 the mill was renamed Lukens Iron and Steel.
