John Oster launched a line of ladies hair clippers in 1924, and, in 1946, he wanted to get Oster Manufacturing Products into the small household electrical appliances market, too. Oster had engineers experiment with ways to reduce foods to a fluid state, and from their research, the Osterizer Blender was born.
In 1955, engineers further improved the original unit and developed a two-speed model. Thanks to advances in technology, what started out as a humble, basic blender has morphed into the chopping, grating, grinding, and pureeing miracle machine we still use (and love!) today.
