History
The first electric blanket was invented in 1912 by American physician Sidney I. Russell. This earliest form of an electric blanket was an ‘underblanket’ under the bed that covered and heated from below. There is some dispute about when the first electric overblankets were introduced. The first recorded publication of such a unit was in 1930 by Samson United Corporation. However, others claim it was later in 1937 that electric 'overblankets', which lie on top of the sleeping person, were introduced in the United States.

However, the two sides are not to be divided off; as long as men exist the history of nature and the history of men are mutually conditioned.”
