I also checked Berkshire Hathaway (1889). It actually goes back to 1839. But does a series of mergers and acquisitions actually count here? The modern form came from Warren Buffett buying shares in it in 1962, and eventually buying them out years later. Buffett's version of the company has pretty much no resemblance to the company he bought out, they aren't at all in the same business, and he mentioned in 2010 that BH was more of a hindrance than a help. https://en.wikipedia.org/wiki/Berkshire_Hathaway#History https://en.wikipedia.org/wiki/Berkshire_Hathaway#History Notably absent from the list are behemoths of the past, like RCA, Kodak, Sears, IBM, Ford, GM, US Steel, Union Pacific, etc.
