## History
### 20th century

Air Products was founded in Detroit in 1940 by Leonard Parker Pool with the objective of establishing on-site production and sales of various forms of industrial gas.
The following year, in 1941, the U.S. entered World War II, and Air Products began manufacturing mobile generators for the production of oxygen used in high elevation military flights and necessary to meet the needs of the U.S. Air Force and allied air forces.
In 1944, the company relocated its headquarters from Detroit to Chattanooga, Tennessee, where it expanded its oxygen production manufacturing capacity to meet the needs of the U.S. military and its allies in their war against Nazi Germany and the Axis powers.
Following the end of World War II, the company relocated its headquarters and operations to Emmaus, Pennsylvania in the manufacturing-intensive Lehigh Valley region of eastern Pennsylvania. In the late 1950s, it completed the development of its current corporate headquarters in neighboring Trexlertown.
Air Products serves customers in technology, energy, healthcare, food, and industrial markets worldwide with atmospheric industrial gases, including oxygen, nitrogen, argon, hydrogen, and carbon dioxide, process and specialty gases, performance materials, and chemical intermediates.
Air Products produces refinery hydrogen, liquified natural gas technologies and equipment, epoxy additives, gas cabinets, advanced coatings, and adhesives.

In 2001, Air Products Received an Award of Merit from the WateReuse Association for Outstanding Water Conservation Efforts for conserving 62 million US gallons (230,000 m$^3$) of drinking water annually by converting to recycled water for the cooling process at its Santa Clara, California manufacturing facility. The award was presented during the 25th Annual WateReuse Symposium. WRA recognizes projects that have advanced the acceptance of water reuse through education, sound science, and technology using reclamation, recycling, reuse, or desalination for the benefit of the public and the environment.
Air Products provided the liquid hydrogen and liquid oxygen fuel for the Space Shuttle external tank. Air Products has had a working relationship with NASA for five decades, supplying the liquid hydrogen used for every Space Shuttle launch and the Mercury and Apollo missions.
Air Products is included on the Dow Jones Sustainability North America Index as one of the best performing sustainable companies for the period of 2008 to 2011.

In 2010, Air Products was awarded the Rushlight Hydrogen and Fuel Cells industry award for the Series 10 hydrogen fuelling station, which celebrates the leading environmental technologies and innovations by organizations throughout the United Kingdom and Ireland by promoting development in hydrogen and fuel cells and enabling further development and funding to be granted toward reducing carbon emissions.
In March 2010, Corporate Responsibility magazine named Air Products to its 100 Best Corporate Citizens List.
In 2013, Air Products' high purity built-in purifier argon was used to determine a more accurate value for the Boltzmann constant.
In September 2015, Air Products announced its intent to spin off its Materials Technologies business. This new stand alone company was named Versum Materials. The spinoff was completed on October 3, 2016. Versum was later acquired by pharmaceutical company Merck.
In January 2017, Air Products completed the sale of its Performance Materials division to Evonik, leaving the company focused on its industrial gases business.
Air Products initially refused to cease operations in Russia in response to the 2022 invasion of Ukraine and the international sanctions subsequently levied against Russia. However, according to Yale School of Management, the company reversed its position and has since divested its interests in Russia.
