Linde Plc
One of the world's largest industrial gas companies, Linde supplies oxygen, nitrogen, argon, hydrogen, and other gases used in healthcare, electronics, food, and steelmaking. It traces to German engineer Carl von Linde, whose first job was building a refrigerator for a Munich brewery in 1873 so lager could be brewed year-round; he founded the company in 1879. The modern Linde plc formed in 2018 when Linde AG merged with Praxair, a US offshoot rooted in a business Carl von Linde started in 1907.
