Retired from SRI International

In 1989, Elizabeth Feinler retired from SRI International, closing out a remarkable 29-year career at the institution and bringing to an end her 16-year tenure leading the Network Information Center (NIC). Her retirement marked the conclusion of a period during which she and her team had built and maintained the essential naming, directory, and information services that allowed ARPANET — and subsequently the early internet — to function as a coherent, navigable network.

Under her leadership, the NIC had grown from a small documentation effort into an essential piece of internet infrastructure, managing host naming registries, developing the precursors to the WHOIS directory service, and helping establish the top-level domain system still in use today. By the time of her retirement, the internet was on the cusp of the explosive commercial and public growth that would define the 1990s.

Feinler's retirement did not mark an end to her influence; her foundational work continued to underpin internet governance and infrastructure for decades afterward. Organizations like the Internet Corporation for Assigned Names and Numbers (ICANN), founded in 1998, would go on to formalize and expand upon the naming and registration systems she helped pioneer.

While the exact month and day of her retirement are not documented in available sources, 1989 stands as a clear marker of the end of an era in which Feinler's leadership was central to the internet's formative development, just before the World Wide Web brought the network to a global public audience.
