Greetings:
I ran across this interesting
wall chart entitled "History of Programming Languages."
It is available for free as a download in PDF format.
It runs from 1954 through 2004.
Pascal, for
instance, which is the language that RF Workbench
was written in, was born in 1985.
"C" began
life as CPL in 1963, then transmogrified to BCPL
(1967), then actually to "B" in 1969, then to "C"
in 1971. The infamous K&R version hatched in
1978.
FORTRAN is the first programming language
on the chart, having begun in November of 1954.
