Dewar was a British chemist and physicist best known for his work on the properties of matter at very low temperatures and the liquefaction of gases.

Used for storing liquefied gases, his Dewar flask—a double-walled flask with an insulating vacuum between the inner and outer walls—became essential in low-temperature scientific work. What everyday item was patterned after Dewar's flask?
