Did you know2023
Air Liquide is known as one of the world's largest industrial gas companies — yet via its VitalAire/Air Liquide Healthcare division, it is also a major home healthcare services provider. Air Liquide Healthcare provides CPAP therapy to approximately 1.8 million sleep apnea patients in France and other countries, including equipment delivery, patient monitoring, and clinical support. It also provides home oxygen therapy for COPD patients, home mechanical ventilation, and enteral nutrition services. An industrial chemistry company is the largest home health care organization for respiratory patients in France — dispatching CPAP machines, oxygen concentrators, and nutrition pumps to private residences with more patient touchpoints than many hospital systems.
L'Air Liquide S.A. ↗Origin2023
Air Liquide was founded in 1902 in Paris by Georges Claude (who also invented neon lighting) and Paul Delorme after Claude successfully liquefied air — the same fundamental technology that Linde AG developed in Germany three years earlier. Air Liquide and Linde (along with their respective descendants) have been the world's two largest industrial gas companies for over a century. Air Liquide has been listed on the Paris stock exchange since 1913 and is one of the few major industrial companies with over 100 years of continuous exchange listing. The company's global expansion to 80+ countries was driven by on-site gas supply contracts with large industrial customers that create switching costs and recurring revenue.
