"Jan Gehl first published his influential Life Between Buildings in Danish in 1971... For more than 40 years, Mr. Gehl has systematically studied public spaces to see how they really work, using Strøget and Copenhagen as a laboratory for his research. He has advised cities around the world, including Melbourne, London and New York, on how to improve the quality of urban life -- in his words, how to Copenhagenize their cities."
