The subject of Chandler Burr's The Emperor of Scent, Luca Turin is a biophysicist with a love of all things olfactive. He started his famous perfume column for NZZ Folio in 2003 and was immediately respected for his honesty. With words that can cut you down to size, but still winking at the same time, he is a popular speaker and writer. When someone has spent thirteen years discussing perfume, I wondered what more we would learn during the Emperor's "Stephan's Six"?
