On this day in 1859, a fellow named George B. Simpson was awarded U.S. patent #25532 for an “electro-heater’ device heated by a platinum-wire coil and powered by batteries. According to his patent application, this device could be used to “warm rooms, boil water, (and) cook victuals.” Not much more is known about George B. Simpson, but his invention lives on in the myriad devices that use electricity to heat food today.
