Early Years (1924–1945)

John Oster founded the John Oster Manufacturing Company in 1924. The company’s first products were manually operated hair clippers for professional barbers. In 1928, Oster introduced one of the first portable motor-driven electric hair clippers, helping establish the brand as a leader in professional grooming equipment. [1]

Expansion into Kitchen Appliances (1946)

A major milestone came in 1946 when Oster acquired the Stevens Electric Company, inventor of an early liquefier blender. After the acquisition, Oster launched the Osterizer® Blender, which quickly became one of the most recognizable blenders in American kitchens.

The Osterizer gained popularity because of its:

• Powerful electric motor

• Durable glass jar

• Replaceable blade assembly

• Long service life

Many vintage Oster blenders from the 1960s–1980s remain operational today, contributing to the brand’s reputation for durability. [1]

Ownership Changes

In 1960, Oster was acquired by the Sunbeam Corporation. Through a series of corporate mergers and acquisitions, the brand eventually became part of Newell Brands, which continues to own and operate the Oster brand worldwide. [1]
