After completing his studies, Robert began working at AT&T Bell Laboratories and also started teaching at the Massachusetts Institute of Technology (MIT). He also had the opportunity to work at BBN Technologies. In the early 1970s, Kahn joined the Defense Advanced Research Projects Agency (ARPA), where he played a key role in the creation of the ARPANET, the first network that connected 40 servers. It was during this time that he began collaborating with Vinton G. Cerf.

Contributions to the Internet

Together, Kahn and Cerf addressed the challenge of compatibility between different channels and networks, leading to the development of the Transmission Control Protocol (TCP) and Internet Protocol (IP), which form the foundation of today's Internet. Their work laid the groundwork for the Internet as we know it today.

Later Career

After spending 13 years at ARPA, Kahn became the director of the Strategic Computing Initiative. He then transitioned to the Corporation for National Research Initiatives (CNRI), where he continues to serve as the chairman. Throughout his career, Kahn and Cerf received numerous awards and honors for their contributions to computer science. Kahn holds honorary doctorates from various universities, including Princeton University, University of Pavia, Eidgenössische Technische Hochschule (ETH), University of Maryland, George Mason University, University of Central Florida, and University of Pisa. He also received the Japan Prize and currently serves on the board of directors of Qualcomm.


Despite his significant contributions to modern computer technologies, there is limited accessible information about Dr. Kahn. Some believe that this lack of information stems from his extensive work on military-funded research projects at ARPA. Nevertheless, Bob Kahn's contributions to the development of the Internet are widely recognized and continue to impact the world.
