The world’s first patent for a household electric stove was issued to David Curle Smith, the Kalgoorlie Municipal Electrical Engineer, in November 1905. About fifty appliances were then built and leased to customers in Kalgoorlie in the following years. The design lacked a thermostat – the temperature was controlled by the number of elements in use.
I am indebted to Howard Willis for telling me about the Kalgoorlie electric stove. Howard wrote the introduction for the reprinted version of Helen Nora’s cook book and supplied a copy of the original patent drawings. He told me:
“My interest in this story came when, in editing a book about a town near Kalgoorlie, I had to look through some newspapers in order to check some of our author’s work. Looking through old newspapers is a very risky business … especially such full-blown pieces of ratbaggery as the Kalgoorlie Miner and the Kalgoorlie Sun of 100 years ago. It took me a few months to discover the full story of the Kalgoorlie stove and the people associated with it, but once I found the cookbook I knew we could reprint it and, with a fairly long introductory essay, give long overdue credit to David and Helen Nora Curle Smith. I was greatly encouraged by the late Dame Elisabeth Murdoch and Ian Murdoch (Sir Walter’s grandson).”
The first heat-regulated electric stove patented in the USA, in 1915, incorporated a thermostat. Its inventor, Lloyd Copeman, eventually sold his patent to Westinghouse, and the rest is history.
