In 1912, S.I. Russell invented and patented an electric heating pad for patients who had tuberculosis. The electric heating pad mad of a small square of fabric with insulated heating coils was designed to help them breathe and keep their chests warm. Amazingly the heating pad sold for $150 which was really pricey for the time. In the 1930’s due to popular demand and lower manufacturing costs, the first electric blanket came to market.

Today you can find electric blankets  in most department stores and online with a variety of features and options, making them a desirable addition to a cold winter night.
