   In 1973, after doing interactive flight simulation over the ARPAnet,
   I joined ISI and applied that experience to interactive speech over
   the ARPAnet.

   The communication requirements for realtime speech were unique (more
   like UDP than like TCP).  This got me involved in the Network Working
   Group, and I started another project at ISI called "Internet

   In 1977 Steve Crocker, who was then at ISI, told me that Jon was
   willing to join us, and that Jon will be a great addition to my
   Internet Concepts project.  Steve was right on both accounts.

   Jon and I worked together from 1977 until 1993 when I left ISI.
   According to ISI's management Jon worked for me for several years,
   and I worked for him for several years.  In reality we never worked
   for each other (nor for ISI), we always worked together, to advance
   the technology that we believed in.  Over most of those 16 years we
   had our offices together, and always worked with each other, even
   when we worked on totally different projects.

   Jon was always most pleasant to work with.  He was most caring both
   about the project, and about the individuals on the team.  He was
   always full of great intentions and humor.  Jon was always ready for
   mischiefs, one way or another.  He was always game to hack something.

   When I worked on the MOSIS project, in 1980, users submitted their
   VLSI designs to us by e-mail.  For several defense contractors,
   getting access to the ARPAnet was too complex.  We suggested that
   they would use a commercial e-mail service, like TELEmail, instead.

   Then we had the problem of getting all the e-mail systems to
   interoperate, since none of them was willing to interoperate with the
   others.  Jon and I solved this problem during one long night of
   hacking.  This hack later became the mail-tunnel that provided the
   service known as "InterMail", for passing e-mail between various
   non-cooperating systems, including systems like MCImail and IEEE's

   I'm sure that Jon was so enthusiastic to work with me on it for two

      * Such interoperability among heterogeneous e-mail systems
        was our religion, with no tolerance for separatism;

      * We definitely were not supposed to do it.

   Jon hated bureaucracy and silly rules, as Cary Thomas so well
   described.  Too bad that we lived in an environment with so many

   We started Los-Nettos without lawyers and without formal contracts.
   Handshakes were good enough.  At that time several other regional
   networks started around the country.  Most of them were interested in
   expansion, in glory, and in fortune.  Jon was interested only in
   getting the problem solved.

   This was Jon's priority, both at work, and in his life.

   I find it funny to read in the papers that Jon was the director of
   IANA.  Jon was IANA.  Much more important, Jon was the corporate
   memory of the Internet, and also the corporate style and the
   technical taste of the Internet.

   Jon was an authority without bureaucracy.  No silly rules!  Jon's
   authority was not derived from any management structure.  It was due
   to his personality, his dedication, deep understanding, and demanding
   technical taste and style.

   Jon set the standards for both the Internet standards and for the
   Internet standardization process.  Jon turned the RFCs into a central
   piece of the standardization process.

   One can also read that Jon was the editor of the RFC, and may think
   that Jon checked only the grammar or the format of the RFCs.  Nothing
   could be further from the truth, not that he did not check it, but in
   addition, being the corporate memory, Jon had indicated many times to
   authors that earlier work had treated the same subject, and that
   their work would be improved by learning about that earlier work.

   For the benefits of those in the audience who are either too young or
   too old to remember let me recall some recent history:
