At the risk of going further off topic:
BCPL was created c1965 by Martin Richards as an implementable subset
of Strachey's CPL.
B was essentially BCPL with {} for the block delimiters instead of $(
and $) (ASCII was fairly uncommon in 1965).
C was derived from B by Dennis Ritchie for the reimplementation of
Unix c1971.

The original Unix (spelled Unics BTW) was developed by Ken
Thompson. I'm not sure who this Pike is.
BTW Thompson and Ritchie had both worked on the Multics project at
Bell Labs.

And I can recall a benchmark of a dual CPU Multics system with c1MB
supporting 200 users. Compare to today's Unices Multics was a resource
miser.
