Daniel Lewin

Lewin was born on May 14, 1970, in Denver, Colorado, to a Jewish family and was one of three brothers. He moved to Israel with his family at age 14 and spent the remainder of his childhood living in Jerusalem. He completed his secondary education at an ORT high school.^[4][5][6]

After finishing high school, Lewin was drafted into the Israel Defense Forces (IDF) and served in the elite Sayeret Matkal commando unit, eventually becoming an officer.^[4] Lewin rose to the rank of captain.^[2]

After being discharged from the army, Lewin studied electronic engineering at the Technion – Israel Institute of Technology in Haifa while simultaneously working at IBM's research laboratory in the city, where despite his simultaneous university studies he became a full-time research fellow and project leader.^[7] While at IBM, he developed the Genesys system, a processor verification tool widely used within IBM and in other companies such as Advanced Micro Devices and SGS-Thomson.^[8][5]

Lewin received a Bachelor of Arts and a Bachelor of Science, summa cum laude from the Technion and was named as the university's outstanding student in Computer Engineering in 1995.^[7] He moved to Cambridge, Massachusetts in 1996 to begin graduate studies toward a Ph.D at MIT. While there, he and his advisor, Professor F. Thomson Leighton, developed consistent hashing, an algorithm for optimizing Internet traffic.^[9] These algorithms became the basis for Akamai Technologies, which they founded in 1998.^[8] Lewin was the company's chief technology officer and a board member, and accumulated substantial wealth during the Internet boom.^[10]

Lewin was reportedly stabbed aboard American Airlines Flight 11 during its hijacking in the September 11 attacks while traveling to a business meeting in Los Angeles.^[11] A 2001 FAA memo suggests he may have been stabbed by Satam al-Suqami after attempting to thwart the hijacking. According to the memo, Lewin was seated in business class in seat 9B, near hijackers Mohamed Atta, Abdulaziz al-Omari, and al-Suqami. Initial reports indicated that he had been shot by al-Suqami, but the final draft of the memo omitted all references to gunfire.^[12]

According to 9/11 Commission Report, Lewin was stabbed by one of the hijackers, likely Satam al-Suqami, who was seated directly behind him.^[13] Flight attendants who contacted airline officials from the plane reported that Lewin's throat was slashed, presumably by the terrorist sitting behind him.^[14]

The 9/11 Commission speculated that Lewin, being a veteran of the Israeli military, may have attempted to confront Atta or Omari, who had been seated in front of him, unaware that al-Suqami was sitting just behind him.^[13] Lewin was identified as the first victim of the September 11 attacks.^[2][3][15]

Lewin was survived by his wife Anne and his two sons, Eitan and Itamar, who were five and eight years old, respectively, at the time of the attacks.^{[4][8][15][16]}

In July 2004, it was reported that Lewin's recovered remains had been identified from Ground Zero.^[17]

Canadian actor Brad Hampton portrayed Lewin in the BBC docudrama Zero Hour Season 1: Episode 2 (2004) called "The Last Hour of Flight 11".^[18]

After his death, the intersection of Main and Vassar Streets in Cambridge, Massachusetts, was renamed Danny Lewin Square in his honor.^[16] The award for the best student-written paper at the ACM Symposium on Theory of Computing (STOC) was also named the Danny Lewin Best Student Paper Award, in his honor.^[9] In 2011, on the tenth anniversary of his death, Lewin's contributions to the internet were memorialized by friends and colleagues.^[19][20]

At the National September 11 Memorial & Museum, Lewin is memorialized at the North Pool, on Panel N-75.^[21]

Lewin is the subject of the 2013 biography No Better Time: The Brief, Remarkable Life of Danny Lewin, the Genius Who Transformed the Internet by Molly Knight Raskin.^[22] According to Raskin, "Because of Akamai, almost every major news site remained up and running [on September 11], a feat that proved everything Danny promised to be possible".^[11]
