Who invented the electric blanket?

The first crude electric blanket was invented in the early 1900s. The heated bed coverings bore little resemblance to the electric blankets we are familiar with today. They were big and bulky heating devices that were dangerous to use, and the blankets were really considered an oddity.In 1936, the first automatic, electric blanket was invented. It had a separate thermostat control which automatically turned on and off, in response to room temperature. The thermostat also served as a safety device, turning off if hot spots in the blanket occurred. Later, thermostats were wired into the blankets and multiple thermostats were used. This basic design remained until 1984, when thermostats-free electric blankets were introduced. In 1946 the first automatic electric blanket went on sale in the US for $39.50, in Petersburg, Virginia. And that an inventor called S. I. Russell patented an electric blanket and some consider him the inventor of the electric blanket.
