Episode 218: Thermos

(Intro & piano music)

We are counting down to the end of this season and as summer seems to be already here, our last three words are dedicated to it. In 1892, James Dewar, a Scottish scientist working in Cambridge, invented an insulated vessel for liquified gasses. What he didn't do is secure the patent for it. 11 years later, in 1903, the German glass blower Reinhold Burger, received the German patent for a vacuum flask to be used as a household item and, created the company that mass manufactured it. Dewar sued for claim to intellectual rights but lost. The name of the flask was put to public competition and the Greek word for 'Hot' won. Stay hydrated everyone! ΘΕΡΜΟΣ/THERMOS
