George Huntington Hartford (September 5, 1833 – August 29, 1917) headed the Great Atlantic and Pacific Tea Company (A&P) from 1878 to 1917. During this period, A&P created the concept of the chain grocery store and expanded into the country's largest retailer. He joined the firm as a clerk in 1861 and quickly assumed managerial responsibilities. When A&P's founder, George Gilman, retired in 1878, Hartford entered into a partnership agreement and ran the company until the founder's death in 1901. In the settlement of Gilman's estate, Hartford acquired control of the company and ultimately purchased the interests of Gilman's heirs.
