(about B and C)
Its history is deeper than that. Its part of a family
of bracketed languages that started with BCPL which became "B" and then
"C".
BCPL was written for the IBM7090.
I think you are mistaken about this - BCPL was an implementation language for CPL mainly
on the Atlas computers.
It was originated by Martin Richards - who is still a supporter ? see
