  • Interesting fact: Hostess Twinkies were invented in 1931 by James Dewar, manager of Continental Bakeries' Chicago factory. He envisioned the product as a way of using the company's thousands of shortcake pans which were otherwise employed only during the strawberry season. Originally called Little Shortcake Fingers, they were renamed Twinkie Fingers, and finally "Twinkies."
    • Dewar A double-walled glass vessel for holding liquid air, liquid nitrogen, etc., having the space between the walls exhausted so as to prevent conduction of heat, and sometimes having the glass silvered to prevent absorption of radiant heat; -- called also, according to the particular shape, Dewar bulb Dewar tube, etc.
