What is Daniel Lewin known for in computer science?
He co-developed consistent hashing, which helps distribute requests and cached content while limiting how much work moves when servers are added or removed. That idea became part of the technical foundation of Akamai's content-delivery network.

Did Daniel Lewin have a research background before Akamai?
He studied at the Technion and moved to MIT for graduate work in 1996, where he developed consistent hashing with Leighton. His master's thesis later became a basis for Akamai's founding in 1998. [MIT News](https://news.mit.edu/2011/remembering-danny-lewin)
What happened to Daniel Lewin in 2001?
Lewin died on September 11, 2001, while traveling on American Airlines Flight 11. Akamai and MIT later commemorated his work through awards and memorials. [MIT News](https://news.mit.edu/2011/remembering-danny-lewin)
