Pieter Hintjens, whom you are referring to, was actually not so much involved in the development of the core ZeroMQ library, though he certainly contributed. His main role was building a community and he did develop a high level C binding czmq. Martin Sustrik was actually what could be referred to as the lead engineer for the initial ZeroMQ project, though he left it quite some time ago.
