Frank Heart, Who Linked Computers Before the Internet, Dies at 89

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.

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).
