I feel I have to provide corrections to your statement.
The modern OSes Windows and Linux were developed by Microsoft Corporation, founded in part by Bill Gates, and by a group led by Linus Torvalds respectively, but neither of these was among the first operating systems. Those began in the days of big mainframes. Though significantly simpler, they were fully functioning software components necessary to get computers to be able to run various programs, rather than the much more simplistic computers to precede them. Linux was built on the model of Unix and CP/M, which both existed as far back as the 1960s, and Windows was built in response to Apple's Macintosh GUI interface, which itself took from work being done at MIT and Xerox PARC in the 1970s. So no, neither one developed OSes in general, just those particular ones.
And the Internet has existed since the 1960s, starting as ARPAnet, for use by the US military and a few Universities working with the Department of Defense on various projects, and expanded significantly to be used by many major US universities, military bases, government offices, large corporations, and even large police departments around the world before it got backing to be opened much more to the public by the 1980s. Tim-Berners Lee utilized Hypertext Transfer Protocol to develop the World Wide Web protocols, to establish easily navigable interfaces, his webpages, for use mostly by CERN scientists using the already established and quickly growing Internet.
All are important parts of making computers and the Internet what they are today, but none are originators of it. Although, Alan Turing's work did do quite a lot in the very early development of electronic computers in the first place, and quite probably not a single name of that era of computer science is as well known to the general public. Not even Grace Hopper . . . who yes, did a lot more than debug one of the early computers. (ENIAC or UNIVAC, but I can't recall which one.)
