The hair dryer was actually invented in 1890 by Alexander Godefoy, but it didn't go public until 1920 when it was more efficient. Before 1920, women were basically using vacuums to dry their hair. This new invention, even though it overheated easily and was very large, was a big hit for the women. Hand held hair dryers came out in 1951.
