Vint Cerf, Father of the Internet, Retires from Google

Vinton Cerf, co-creator of TCP/IP and Google's chief internet evangelist since 2005, announced his retirement at age 83, closing one of the longest-running careers in networking history.

Vinton Cerf, the computer scientist who co-designed the TCP/IP protocols that serve as the foundation of the modern internet, is stepping down. At 83, Cerf announced he will retire from his role as Google's chief internet evangelist — a position he has held since 2005 — marking the end of a career that spans the entire history of the network he helped build.

Together with Bob Kahn, Cerf created TCP/IP in the 1970s while working at DARPA. Those protocols remain the universal language through which every device on the internet communicates. For that work, he earned the moniker "Father of the Internet," along with the Turing Award (2004), the Presidential Medal of Freedom, and the National Medal of Technology.

At Google, Cerf's role was far from honorary. He was a vocal advocate for network neutrality, accessibility standards, and the expansion of internet infrastructure worldwide. He pushed for the adoption of IPv6 as the IPv4 address space exhausted, and championed the Interplanetary Internet — delay-tolerant networking protocols designed to extend connectivity beyond Earth.

TechCrunch, which published the exclusive, reports that Cerf began his career in 1969 on the ARPANET project, the Pentagon-funded precursor to the internet, and has been present for every major inflection point since: the shift from military-academic origins to the commercial web, the mobile revolution, and the emergence of AI-scale data centers.

His departure leaves vanishingly few members of the internet's founding generation still active in the industry. Cerf has indicated he will continue advisory work and pursue interests in space-based networking.
