<div dir="ltr">Bob Kahn was at MIT faculty then BBN and joined ARPA in late 1972 after managing the ARPANET demonstration at ICCC 92 in Washington, DC. I joined Stanford as an assistant professor in later 1972 after 5 years at UCLA working on MS/Ph.D. in computer science. I joined bob at arpa in mid1976. Bob never managed the ARPANET project but was a key architect of the IMP while at BBN. and initiated the Internet project at ARPA in early 1973.<div>

</div>A footnote -- this was also true within BBN. The IMP guys weren't the<br>
