From page 89 of TBL's "This for everyone": "Estimates vary, but only around 2 million people regularly used the internet in 1991 — approximately 0.03 per cent of the Earth’s population. Most of them were academics, since the internet hadn't yet been formally opened to the public, and the concept of an Internet Service Provider (ISP) was still in its infancy. One of those early users was Paul Kunz, a particle physicist and software developer at the Stanford Linear Accelerator Center (SLAC) in Menlo, California.
Paul visited CERN for unrelated business in 1991, but, as I knew he was a NeXT enthusiast, I was able to corral him for a quick demonstration of the World Wide Web. Paul used a NeXT at CERN to log into his own computer in California remotely, then downloaded the web app remotely. He loved how fast it was, even when browsing web pages across the Atlantic. Like Robert Cailliau, Paul got it instantly, and evangelized for the technology upon his return to Stanford, With the help of SLAC librarian Louise Addis, Paul encoded a large number of scientific papers into HTML, then created a web page at http://slacvm.slac.stanford.edu."
Starting the fourth chapter "The Rise of the Web" of #ThisIsForEveryone, I am pleasently surprised to find out a librarian — Louise Addis of the Stanford Linear Accelerator Center (SLAC) — played an important, supportive role in the very first days of the web.
