David J. Farber, a respected computer networking professor often referred to as the “grandfather of the internet,” has passed away at the age of 91. Farber died on February 7 in Tokyo, where he had been teaching at Keio University since 2018.
Farber earned recognition not only for his own work in computer networks but also for mentoring students who later became key figures behind the development of internet protocols. His contributions helped shape the early architecture that eventually evolved into the modern internet.
A Mentor Behind Internet Protocol Innovation
During his academic career, Farber guided researchers who would go on to build foundational technologies of the internet. Among his students were innovators linked to the development of the Internet Protocol (IP) and the Domain Name System (DNS), both of which remain core elements of today’s online world.
In the early 1970s, collaborative discussions between Farber and his students contributed to ideas that defined how computers communicate through data packets — concepts that later became essential to global networking.
Early Vision: Computing Meets Communication
Farber began his career in the 1950s at Bell Laboratories, when computers functioned largely as isolated machines. Over time, he advocated for the idea that computing and telecommunications would eventually merge — a vision that proved critical in the rise of email, online communication, and digital collaboration.
His research and policy work helped attract support for early experimental networks and projects that connected universities and research centers, laying the groundwork for broader internet adoption.
Expanding the Internet Beyond Research Labs
As internet technology matured through the 1980s and early 1990s, Farber continued contributing to policy and educational efforts that supported expansion beyond academic institutions. He later served in leadership and advisory roles related to internet regulation and technology policy.
Colleagues often described him as someone who balanced technical expertise with a strong focus on the human side of technology — believing the internet’s real value came from how it connected people.
A Lasting Legacy
David J. Farber’s influence extended far beyond research papers or patents. Through mentorship, advocacy, and forward-looking ideas, he helped shape the evolution of modern networking and inspired generations of computer scientists.
His legacy continues through the technologies and communities that power the internet today.
