Paul Kunz (December 20, 1942 – September 12, 2018) was an American particle physicist and software developer, who initiated the deployment of the first web server outside of Europe. After a meeting in September 1991 with Tim Berners-Lee of CERN, he returned to the Stanford Linear Accelerator Center (SLAC) with word of the World Wide Web. By Thursday, December 12, 1991, there was an active Web server installed and operational at SLAC, establishing the first Web server in the US, the SPIRES HEP, connected to the SPIRES High Energy Physics database, thanks to the efforts of Kunz, Louise Addis, and Terry Hung.
