What did James Dewar invent?

I remember when the thermos was fragile and had to be treated very carefully if not you would not have it for long...that was back a long time ago....in the so called good old days!

mackerounski, Another invention the Americans stole , and now they whine about the Chinese doing the same

another Scottish invention what we gave to the world is incredible

Player #1489294, I added mine to your number of thumbs up & thought to myself what a lot of elderly players of this quiz there must be considering the large number!! Definitely the best group though!!

JezzerLX, I got a real thermos from LLBean. keeps things cold for 24 hours.

thought he must have admitted the house to keep his whiskey in

been there my DAD LOST cause no patent

so not Dewar as in Dewar's and water?

tystyx, MY THOUGHT EXACTLY!!! lol
