Whatever you mean by template, I don't think he invented them.
- If you mean "parametric polymorphism", Strachey introduced his
classification in 1967, when A.Stepanov was 17, and I think Strachey
classified notions which where already existing.

- If you mean the specific of C++ way, I suggest reading the section 4.1.2
of http://www.research.att.com/~bs/hopl-almost-final.pdf
where you'll find
that while he was working at Bell Labs at the time when C++ template where
designed, he failed in convincing Bjarne Stroustrup to make that mecanism
more similar to Ada generics. BTW, it is that difference which make the
STL
so more friendly than his earlier work in Ada.
