Who invented the can and the can opener and in which year?

Answer 1

Somewhere around 1772 , the first can openers were patented only in 1855 in England and in 1858 in the United States. Those openers were basically variations of a knife, and the 1855 design continues to be produced. The first opener employing the now familiar sharp rotating wheel, which runs around the can's rim cutting the lid, was invented in 1870 but was difficult to operate. A breakthrough came in 1925 when a second, serrated wheel was added to hold the cutting wheel on the rim of the can. This easy to use design has become one of the most popular can opener models.

Answer 2

The can opener that most of us still use today was invented in 1870 by William Lyman. The first electric version of this design wasn't produced for over a half century later, in December of 1931.
