Who invented the tin can?
Canning was invented in 1809 by Nicholas Appert. His process was moderately successful and adopted by Europe and the United States. The glass containers that were first used proved bulky, costly, and brittle, but the early methods of making cans weren’t much better. Sheets of tin were cut with shears, then bent around a block and the seams heavily soldered. A good tinsmith could make only about 60 cans a day. The industry grew with the 1847 invention of the stamped can. Civil War soldiers were supplied with canned meats and vegetables using this method. A machine for shaping and soldering the cans automatically was exhibited in 1876 at the Centennial Exposition in Philadelphia.
