The Danny Lewin Park in Cambridge, MA was just redone: www.cambridgeredevelopment.org/danny-lewin-park-enhancement.

Highly recommend his biography, "No Better Time: The Brief, Remarkable Life of Danny Lewin."

He was a commando turned computer scientist turned billionaire who died fighting terrorists at the age of 31. And, remarkably - 9/11 was a big turning point for Akamai because it was a first news event that people monitored using the internet, so many news websites had to turn on Akamai to handle the traffic surge.
