If you've spent your life believing that the Thermos was invented by some guy named Thermos, prepared to have your mind blown: The Thermos, or vacuum flask, was invented by Scottish physicist and chemist Sir James Dewar in 1892. Unfortunately for James Dewar, he failed to register a patent for his nifty invention, which was subsequently patented by Thermos GmbH, the German company that began produced the vacuum flask for commercial use in 1904. And thus James Dewar's invention was known as the Thermos. Poor James.
