Blender - History of Blender
The blender was first invented by Stephen Poplawski, owner of Stevens Electric Company, in Racine, Wisconsin in 1922. He wanted a way to mix up drinks like malts and milk shakes, which had become popular at soda fountain restaurants. He had the idea to put a spinning blade at the bottom of a container, connected to a motor. Poplawski went on to receive patents in 1932 for a machine that would reduce fruits and vegetables to a liquid.
A blender is usually has a container made of glass, plastic, or steel, with a blade at the bottom able to hold 4-8 cups of liquid. There have been many versions and brands over the years. One of the most popular early versions was the "Waring Blendor" (the creating preferred the "blendor" spelling). A partnership between inventor Fred Osius and investor Fred Waring resulted in the development of their version of the blender. Osius invented this version of the blender, and received a patent for it in 1933. The partnership began to suffer though, because of technical problems with Osius' design. Eventually, Waring left Osius and redesigned his blender, and introduced the Waring Blendor to the public 1937.
- The blender would not have come into being without the invention of the small electric motor in 1910. The new motor, which was known as the fractional horsepower motor, made possible the invention of many appliances, including the blender.
- Starting in the 1950s the blender became widely used in hospitals and labs. It was a vital scientific research tool for Dr. Jonas Salk. Dr. Salk used the blender with a particular attachment during the development of the lifesaving polio vaccine.
