Daniel Lewin was among those killed in the hijacked American Airlines flight 11 that crashed in New York. He was a computer scientist whose ideas contributed towards Akamai Technologies' development of a network of servers (now numbering in the thousands) that distribute web content around the globe. "Distributing content intelligently, and keeping it up to date, required a lot of sophisticated mathematics. The development of the technology started at the Massachusetts Institute of Technology (MIT), where Lewin completed his master's degree under Tom Leighton, a professor of applied mathematics," writes Schofield in the Guardian Unlimited. In 1998 Lewin and a team of entrepreneurs raised some venture capital and founded Akamai. This year Lewin was listed in the top 10 of the Enterprise Magazine's ``Power 100'' people for their impact on information technology.
