Edward Ludwig Glaeser (born May 1, 1967) is an American economist and Fred and Eleanor Glimp Professor of Economics at Harvard University. He is also Director for the Cities Research Programme at the International Growth Centre. According to a review in The New York Times, his book titled Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier (2011) summarizes Glaeser's years of research into the role that cities play in fostering human achievement and "is at once polymathic and vibrant".
