Electric stove

In 1896, the first U.S. patent for an electric stove was patented by William.S. Hadaway, Jr., in New York City. (No. 563,032). It provided a uniform surface distribution of heat from a one-ring spiral coiled conductor. An earlier apparatus, described as an "electrical heating apparatus," which the inventor termed an "electroheater," was patented by George B. Simpson of Washington, D.C. on 20 Sep 1859 (No. 25,532).
