Chandler Burr was the New York Times’ first-ever fragrance critic. His knowledge of the history, culture, emotion, economics, science, and global geography of scent may be unrivaled. If you'd like to learn about fragrance - or the science and economics of smell - watch Chandler as he leads the Camden Opera House on an interactive, hyper-articulate, and hilarious olfactory journey. This is one of the best 30 minutes I've spent on the Web.Video courtesy of PopTech
