The Kerr Self Sealing Mason jar was developed by the Hermetic Fruit Jar Company, founded by Alexander Kerr in 1903.

The Self Sealing jar was one of the first products that the company released.

These humble glass pieces were designed for putting up fruits and vegetables in the days before refrigeration.

Kerr did not actually manufacture glass during the earliest period from 1904 to 1909, but instead had jars made for them (with the Kerr name embossing) by other glass companies, Illinois-Pacific Glass Company of San Francisco, and Hazel-Atlas Glass Company based in Washington, PA, later Wheeling WV.

Many of the earlier ECONOMY types are marked with the words “KERR GLASS MFG.
