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.
