Herb Sutter is the WG21 convener. Versions of the C++ programming language are standards from the ISO/IEC Joint Technical Committee JTC1, sub-committee WG21 often referred to as just "the committee" in this context. The convener is in effect head of the committee. For comparison WG14 is the C language commitee.

Herb has made lots of proposals for changing C++ over the past half a decade or so, a few of them have shipped in newer C++ versions, most didn't go anywhere. At CppCon (a big C++ convention) Herb's keynote was about a transpiler which takes a different syntax, including most of Herb's features that didn't make it and some new features, and turns that into C++. This has been referred to as either "cppfront" or "cpp2".
