False - The method of preserving food in tin cans was in use by the Dutch Navy from at least 1772, taking the fact literally, why would anyone preserve food in something that they couldn’t later open? Common sense says that rudimentary can openers have been in use since at least 1772. If the fact was refering to the can openers that you and I know of today, whether it be the non-moving lever type or the rotating wheel type (I think we can safely assume they didn’t mean the electric can opener), the earliest verifiable dates we can use would be when they were patented. Can opening patents began to appear in the 1850s with Robert Yates of the United Kingdom patenting the first lever type can opener in July of 1855, similar to the type you’d find on any boyscout’s multi-tool pocket knife today. A good 83 years after the Dutch Navy first started to pack freshly caught salmon, boiled in brine, smoked in tin-plated iron boxes. The first rotating wheel type of can opener came about roughly 20 years after the first patents of the lever type, but the dual wheel variaty that we know so well today was first patented in 1925 by the Star Can Opener Company of San Francisco, California. A good 153 years after the first cans rolled down the packing line. original claim: @OMGFacts; source: wikipedia
