Early electric stoves
The evolution of the oven has come a long way since the first oven built in 1490 in Alsace, France, which was made of brick and tile. In 1891, the Carpenter Electric Heating Manufacturing Company invented an electric oven, and in 1892, Thomas Ahearn, a Canadian electric company owner, filed a patent for an "Electric Oven". Ahearn's oven was first put into service in 1892 at the Windsor Hotel in Ottawa. An electric stove was also exhibited at the Chicago World's Fair in 1893.
In 1908, three companies in the United States began selling electric stoves, but sales and public acceptance were slow. It wasn't until the late 1920s and early 1930s that electric ovens began to compete with gas ovens. Improvements in electricity distribution, reduced costs, and modernized styling contributed to the increased acceptance of electric stoves. The invention of nichrome alloy for resistance wires also improved the cost and durability of heating elements.
By the 1930s, electric stoves had become more fashionable due to their ease of cleaning, lower prices, and faster cooking times. However, some cooks at the time complained that electric stoves took away the art of cooking, prioritizing time and cost savings over the joy of the culinary process.

The first electric ovens
The evolution of the oven has come a long way, from the basic concept of a stone enclosure with a fire for cooking to the modern electric ovens of today. The first oven in recorded history was built in Alsace, France, in 1490 and was made entirely of brick and tile. Over the centuries, inventors made improvements to ovens, primarily to address the issue of smoke produced by wood-burning stoves.
In the 18th century, Count Rumford of England made significant contributions to oven development by improving the Castrol stove, invented by François Cuvilliés in 1735. Count Rumford's iron stove could heat multiple pots at different temperatures and was the first sign of the modern stoves and ovens we use today.
As gas became a more common fuel source, the focus shifted to gas ovens. In 1826, English inventor James Sharp patented the first semi-successful gas oven, which became commonplace in households by the early 20th century.
However, the development of electric ovens soon followed. Canadian inventor Thomas Ahearn, owner of the Chaudiere Electric Light and Power Company of Ottawa, is often credited with inventing the first electric oven in 1882. Ahearn demonstrated his electric oven in 1892 by preparing a meal entirely with electricity at the Windsor Hotel in Ottawa. The Carpenter Electric Heating Manufacturing Company also invented an electric oven in 1891.
On June 30, 1896, William Hadaway received the first patent for an electric oven, and by the late 1920s, electric stoves began to compete with their gas counterparts. Improvements in the practical application of electricity and the decreased cost of electric power in the 1920s and 1930s made electric ovens more accessible and popular.

Electric oven improvements
Electric ovens were invented in the late 19th century, but they were not widely used in homes until the late 1920s when the practical application of electricity improved. Over the years, there have been numerous improvements to the electric oven, which have contributed to its increased acceptance and popularity.
One of the earliest improvements to the electric oven was the invention of resistor heating coils, which were a familiar design also seen in hotplates. The Carpenter Electric Heating Manufacturing Company invented an electric oven in 1891, and William Hadaway was issued the first patent for an electric oven in 1896. The electric stove was showcased at the Chicago World's Fair in 1893, where an electrified model kitchen was presented.
In 1905, David Curle Smith, the Municipal Electrical Engineer of Kalgoorlie, Western Australia, applied for a patent for a device that adopted the design of gas stoves, which later became the configuration for most electric stoves: an oven with a hotplate and a grill tray between them. Curle Smith's stove did not have a thermostat; instead, heat was controlled by the number of the appliance's nine elements that were switched on. About 50 appliances were produced before cost overruns halted the project.
Another improvement was the invention of nichrome alloy for resistance wires, which improved the cost and durability of heating elements. In the 1970s, glass-ceramic cooktops were introduced, offering faster heating, minimal afterheat, and a smooth, flat surface that was easier to clean. This innovation led to the development of induction stoves, which also have a smooth glass-ceramic surface but require ferromagnetic pots and pans.
Today, most electric ranges have a smooth cooktop surface, which is easier to clean but may not be compatible with certain types of pots and pans, such as enamel-coated cast iron. Electric ovens have come a long way since their invention, and they continue to evolve to meet the changing needs and demands of modern cooking.

Electric oven popularity
The popularity of electric ovens can be traced back to the late 1920s and early 1930s when they started to compete with gas ovens. However, the journey towards their widespread adoption began much earlier.
The first electric ovens were available as early as the 1890s, with Canadian inventor Thomas Ahearn often credited with creating the first electric oven in 1882. Ahearn demonstrated his electric oven in 1892 at the Windsor Hotel in Ottawa, cooking an entire meal with electricity. This was followed by an electric stove exhibition at the Chicago World's Fair in 1893. In 1896, William Hadaway received the first patent for an electric oven, and by the early 20th century, electric stoves were in use, not long after the introduction of home electricity.
Despite these early developments, the widespread adoption of electric ovens was hindered by several factors. Initially, the technology and distribution of electricity needed to power these appliances required improvements. Electric ovens also faced competition from gas ovens, which became common in households by the 1920s due to their ease of use, compact design, and the availability of gas lines.
It was in the late 1920s and early 1930s that electric ovens began to gain traction. Improvements in the practical application of electricity, such as better power supply and reduced costs, made electric ovens more viable for homeowners. Additionally, electric ovens had advantages over their gas counterparts, including easier cleaning, lower prices, and faster cooking times.
By the 1930s, the maturing of electric oven technology, modernized styling, and effective marketing by electrical utilities contributed to their increased acceptance. Electric ovens slowly replaced gas ovens, especially in household kitchens, as they offered a more convenient alternative to solid-fuel stoves that required more labour and maintenance.
Today, electric ovens have continued to evolve, with features such as smooth cooktop surfaces, induction technology, and double wall ovens. The introduction of the microwave oven in the 1940s further expanded the options for electric cooking appliances, solidifying the popularity of electric ovens in homes worldwide.
