That should be Dave Walden, *not* Dave Walker...  mia culpa.

Frank Heart, Who Linked Computers Before the Internet, Dies at 89
https://www.nytimes.com/2018/06/25/technology/frank-heart-who-linked-computers-before-the-internet-dies-at-89.html

Mr. Heart demanded that I.M.P.s be made impenetrable, believing that
curious graduate students would be tempted to poke around the machines
to see how they worked and bring down the network with their tinkering.

... snip ...

former IBM co-worker was UC undergraduate in 1969 and hired to do
IMP/Arpanet penetration testing.

other drift, early 70s, my wife worked for BBN on gov. contracts;
SIGMA5/SIGMA7 lashup, PLI cross-compiler for Litton computers. They then
asked her to go to Cambridge to inteview for the IMP/ARPANET group, but
she didn't want to leave DC area. She eventually left and joined IBM
gburg in 1973 on Future System project, working for Les Comeau (who had
been involved in the original virtual machine implementations at the
cambridge science center).

Of course, Will Crowther is best known for his part in writing Colossal 
Cave Adventure, something it seems he does *not* want to talk about 
publicly.

Bernie Cosell is an MIT alumnus who used to post to <a.f.c.> in years 
past.  He *may* still be lurking, in case anyone slips up and posts 
something related to computers!  :-)

In the book _Coders at Work_, Cosell was interviewed.  He spoke highly 
of Frank Heart and Heart's management style.  The book is a collection 
of 15 interviews with different "famous" programmers.  I recommend the book.

Not to minimize the contributions of Mr. Heart, but the NYT article
above avoids some earlier research in computer routing and networking.

more trivia: when FS blew up ... past posts
http://www.garlic.com/~lynn/submain.html#futuresys

my wife co-authored AWP39 (architecture white paper) "peer-to-peer
networking" with Bert Moldow. They had to qualify it with "peer-to-peer"
because the communication group had co-oped "networking" for SNA (we
joke that it wasn't a system, it wasn't a network and it wasn't an
architecture, it was terminal control infrastrcuture).

she was also one of the "ASP" catchers in the IBM gburg group for
turning into JES3 and co-author of "JESUS" (JES unified systems) ... all
the features of JES2 & JES3 that the respective customers could live w/o
... for various reasons never came to fruition. all sorts of past
HASP, JES, NJI/NJE, etc posts
http://www.garlic.com/~lynn/submain.html#hasp

she then gets con'ed into going to POK to be in charge of
loosely-coupled (mainframe for cluster) architecture where she did
"peer-coupled shared data" architecture. She didn't remain very long, in
part because 1) constant battles with communication group trying to
force her to use SNA for loosely-coupled operation and 2) little uptake
... except for IMS hot-standby, until SYSPLEX and Parallel SYSPLEX.

IMS
https://en.wikipedia.org/wiki/IBM_Information_Management_System
recent availability
https://www.ibm.com/developerworks/community/blogs/RohitShetty/entry/high_availability_cold_warm_hot?lang=en
parallel sysplex
https://en.wikipedia.org/wiki/IBM_Parallel_Sysplex

mid-80s, IMS hot-standby could be up and operational almost immediately
... but it had communication group problem. The stand-by VTAM then had
to recreate all the terminal sessions ... establishing sessions in VTAM
was enormously heavy-weight process ... and for large operations (say a
few tens of thousands of ATM machines) it could take over 90mins.

I was roped into working with a baby bell that had built a NCP/VTAM
emulator on series/1 with a whole bunch of additional features. It ran
real networking between series/1s ... but emulated 37x5/NCP to host VTAM
and spoofed cross-domain ownership of resources (terminals).  Among
other things, it could fake shadow sessions to stand-by machine
... which would make "real" IMS hot-standby almost immediate.

We were working on turning it out as an IBM "TYPE-1" product on Series/1
with follow-on plans to port it to the (unannounced) RS/6000. We had
done everything we thought possible to brickwall off attempts by the
communication group to kill the effort ... what the communication group
did next to kill it can only be described as truth is stanger than
fiction.

What might be the reason for it? AFAIK Colossal Cave Adventure is
considered pure classic now, highly appreciated by all who's familiar with
the genre. I wouldn't see any reason to hide the fact that one helped to
create a whole genre of computer games (or even more than that, since IF
can be looked at as a literature.)

wiki entry
https://en.wikipedia.org/wiki/William_Crowther_(programmer)

I first saw copy of adventure at tymshare in the 70s ... they had got it
off stanford sail pdp10 and ported it to vm370/cms. I get a copy and
made it available on IBM internal systems ... people that can prove they
got all points, I would send source. within short time PLI versions
start showing as well as versions with lots more points.

other trivia; his wife nancy worked for IBM in cambridge
(CROWTHER@CAMBRIDG) ... at the IBM Cambridge Science Center and the IBM
side of Project Athena. Both IBM and DEC had provided $25M to project
athena and got deputy/assist directors ... and provided some number of
additional people ...

project athena 
https://en.wikipedia.org/wiki/Project_Athena

CAS was IBM deputy/assist director at Project Athena.  I periodically
mention him for having invented "compare&swap" instruction when he was
working on fine grain multiprocessor locking for CP67 ("compare and
swap" chosen because they are charlie's initials, CAS).  compare and
swap instruction

for even more drift ... 1999/2000 we were on assignment in Seattle
working with a number of companies on online/internet financial
... including a company that specialized in Kerberos (from project
athena)
https://en.wikipedia.org/wiki/Kerberos_(protocol)

the company had brought in a new CEO ... who had previous been head of
IBM POK mainframe and then head of IBM Boca PS2/OS2 (some accounts from
that period have him in conflict with head of microsoft).  At the time
the company also had a microsoft contract to do the kerberos
implementation/port for windows.
