Guitar-toting director in tune with students

Robert Landau and his family have lived in many countries. If you ask his eldest son where he comes from, he'd say he is a citizen of the world as he was born in Switzerland and grew up in Prague.

Landau is neither a diplomat nor an international correspondent. The American man has 33 years' experience in teaching at, and running, international schools.

Now, he is in China, as director of the Western Academy of Beijing (WAB).
