In 1858, Ezra Warner patented his design for a can opener in America. Tin cans were first invented around 1810 but these cans were very thick and needed hammers and chisels to open. Later in the 19th century, cans became more thin like they are today. I got my information from Wikipedia.
The can opener was invented before the microwave. The first can opener was patented in 1855, while the microwave oven was not invented until 1946. Can openers were developed to open sealed cans, which became popular in the early 19th century for preserving food, whereas microwaves were developed much later as a cooking appliance utilizing electromagnetic radiation.
