American Trading and Production Corporation (Atapco) was originally formed in 1931 to consolidate, expand and diversify the business activities of the Blaustein family, the founders of the American Oil Company (AMOCO). Louis Blaustein started in the oil business by delivering kerosene with his son, Jacob, from a horse-drawn tank wagon through the streets of Baltimore. In 1910, Louis and Jacob founded American Oil in a one-room office in a converted stable. The company gained national recognition for innovation, well-planned and controlled expansion and diversification. Innovations included one of the first drive-in gas stations, the first gasoline pump to show the motorist the amount of fuel received and the original antiknock gasoline that permitted the development of the high-compression engine.
