Who invented iron?

Answer 1

iron was invented Henry Seeley in 1882, in the state of new york. Iron - or the discovery of how to make iron was - unlike other metals - was done by the Hittites who came from c. Turkey / northern Mesopotamia. As far as scientists / archaeologists can determine the discovery of iron happened only once in human history unlike copper or bronze. This may seem unlikely but given the fact that metal working as a whole was unknown (generally accepted to be the case) at all in the American continents, then only one origin for iron working itself is not unreasonable. Given that humans lived in the Americas for 15,000 years but did not work metal suggests that the discovery / ability to work metal (of what every sort) was something that happened rarely in human history and was not something that was 'bound' to happen. The surprise perhaps is that metal working was ever discovered ....
Iron is not an invention. It is a naturally occurring element.

Answer 2

There is no specific person who invented ironing. The earliest acknowledgment of ironing is from the Chinese whom used heated metal to smooth out cloth. Although in 1882 Henry Seely patented the first electric iron.
