They did, of course; Algol after all is the first block structured language, and most block structured languages since then copied its approach to name and data scope. (Not all; for example, Python has scope rules that are noticeably different.)
Then there was Algol 68, which in spite of its name is not all that close to Algol 60. It added a number of innovations that subsequently were adopted by C++. The iostreams mechanism is a rather obvious example (I believe Stroustrup points out the Algol 68 heritage explicitly in one of his books).
