Dan Lynch played a key role in driving global adoption of TCP/IP protocols and fueling the Internet’s commercial success, public visibility, and use. In the 1970s, as director of computing facilities at SRI International, Lynch ran the data center where the second ARPANET node was located, and while there performed initial TCP/IP development. Then, at the University of California’s Information Sciences Institute, he led the ARPANET team that made the transition from the original Network Control Program protocols to TCP/IP. During this period, he launched an effort to track TCP/IP implementation on the ARPANET, which significantly propelled U.S. TCP/IP adoption. He went on to found INTEROP, which played a dominant role in demonstrating the commercial viability of the Internet's design, and trained thousands on the design, implementation, and operation of Internet-enabled equipment.
