[TUHS] List of earliest UNIX licensees?

[George Michaelson via TUHS]

Gosh. If that address list at the end is indicative of recent people

Jeff Tansley at Edinburgh Uni, and Prof Heath at Heriot-Watt. So both
Edinburgh uni were exploring things. And Louvain and Jerusalem uni.  I
think I met Tansley (as a kid probably - I was 14 in 1975. he'd have come
to a garden party or something my parents were very hospitable in the
academic fried finger food and drinks circuit)
