Founded in 1904 in Germany by glassblower Reinhold Burger, Thermos is the progenitor of the insulated vessel, commercializing Sir James Dewar’s vacuum flask technology for the masses. Originally a scientific marvel, the brand quickly became a household staple, equipping everyone from polar explorers to blue-collar workers with the ability to keep "hot things hot and cold things cold." Today, headquartered in the United States and owned by Nippon Sanso, Thermos remains the quiet giant of the category, eschewing the viral marketing of trendier competitors for a reputation built on accessibility and function.
