1940
Leonard Parker Pool founded his company to meet the needs of the mid-level oxygen consumer. Although his idea to combine existing technology with a novel marketing concept was ingenious, immediate orders were not forthcoming. Frustrated but undaunted, Pool seized opportunity and instead, sold oxygen generators to support military efforts during World War II.
Leonard Parker Pool founds Air Products in 1940 in Detroit, Michigan, on a simple, but revolutionary, idea: the "on-site" concept of producing and selling industrial gases.
Air Products leases its first oxygen gas generator to a small Detroit steel company in 1941.
World War II diverts the company's attention to the design and manufacture of mobile generators to produce oxygen for use by the military in high-altitude flights.
In 1944, Air Products moves to Chattanooga, Tennessee and produces 240 oxygen generators for the armed forces and for "lend-lease" to foreign allies.
After the war, the company refocuses its sights on commercial markets by setting up operations near Allentown in Pennsylvania's Lehigh Valley.
In 1945, Air Products secures a contract with Weirton Steel Company in West Virginia to lease three generators that produce six tons per day of oxygen.

In the post-war years, abundant oxygen was transforming the gas industry. Company founder Leonard Parker Pool was determined to compete in this "tonnage" gas market, and his plan proved as inventive as his on-site concept.
