An exact date is unknown. The history of canning includes the following major events:
Napoleon Bonaparte started the world towards the modern preservation of foods when he posted a reward to the person who could preserve food for his army. His army was constantly traveling and food was a problem. He offered the reward in 1795 and in 1810, Nicholas Appert introduced a method of preserving food using heat-processing in glass jars. The jars were sealed with wax.
By the time of the U.S. Civil War glass food preservation jars with metal clamps and replaceable rubber rings had been invented.
In 1858, John Mason invented a glass container with a screw-on thread molded into its top, and a lid with a rubber seal. Wire-clamped were in use until 1964.
In the late 1800s, William Charles Ball and his brothers got into the food preservation jar business.
In 1903, Alexander Kerr invented the wide-mouth canning jar (the Ball company copied this design). The modern 2-piece canning lid was invented by Kerr in 1915.
In the early 1900's.
