In 1892, Scottish scientist Sir James Dewar invented the vacuum flask. Through his work in cryogenics, he identified a need to keep a chemical placed in a flask at a stable temperature. To do this, Dewar placed a glass bottle in another larger glass bottle, and evacuated the air between the two bottle walls. In doing so, Dewar created a partial vacuum to keep the temperature of the contents stable. Hiring a professional glass blower to make a sturdier flask led to the commercial manufacture of the “Dewar Flask” in 1898. |

Reinhold Burger and his business partner Albert Aschenbrenner were manufacturers of scientific glass devices. While producing flasks for Dewar, they crafted a domestic vacuum flask with a protective metal casing and secured a patent for it. |

Burger and Aschenbrenner hosted a competition to find a new brand for the vacuum bottle business. A local resident submitted the word “Thermos”, derived from the Greek word thérmē meaning heat. |

At the start of it all in 1904, the founders domesticated the vacuum insulation technology, creating the first Thermos® product. |
| 1906 |
An American businessman, William B Walker, met Burger on his travels to Berlin. In learning of the “Thermos” brand bottle and realizing the potential market in the United States, he strategically made plans to import, obtained the necessary patent rights, and began raising capital to manufacture in his country. |
