Frequently Asked Questions About History's Greatest Inventions
Which invention had the single biggest impact on human history?
Historians consistently place the printing press (1440) and writing (c. 3400 BC) at the top, because both unlocked the accumulation and spread of every other human discovery. Source: [Encyclopædia Britannica — Gutenberg and the Printing Press](https://www.britannica.com/technology/printing-press).
Did one person invent the internet?
No. The internet evolved from ARPANET (1969), a U.S. Defense Department project. Vint Cerf and Bob Kahn later developed the TCP/IP protocols that knitted those networks into the global internet we use today. Source: [Internet Society — A Brief History of the Internet](https://www.internetsociety.org/internet/history-internet/).
How many lives has penicillin actually saved?
Estimates put the figure at approximately 200 million lives since mass production began in the 1940s, cementing penicillin as one of the most consequential medical breakthroughs in history.
