Timeline of historic inventions

The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and the people who created the inventions.

Note: Dates for inventions are often controversial. Inventions are often invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.

Earliest inventions

The dates listed in this section refer to the earliest evidence of an invention found and dated by archaeologists and seen by the people editing the page. Dates are often approximate and change as more research is done, reported, and seen. Older examples of any given technology are found often. The locations listed are for the site where the earliest solid evidence has been found, but in most cases there is little certainty how close that may be to where the invention took place.
