A two-minute review of his Wikipedia page would answer your question (or ad-hominem attack). If you looking for inventions, he designed and built the first web browser and the first web server[1].

In Tim's words: "I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas and—ta-da!—the World Wide Web."
