The first victim of the 9/11 attacks was a veteran of an elite IDF unit, as well as an innovative Internet entrepreneur By most accounts, Danny Lewin was the first victim of 9/11. Seated in seat 9B aboard American Airlines flight 11, he saw Mohamed Atta and Abdulaziz al-Omari, sitting just in front of him, rise and make their way to the cockpit.

According to calls from flight attendants to air traffic officials, later documented in the 9/11 Commission’s report, Lewin wasted no time in acting. Having served as an officer in Sayeret Matkal, the Israel Defense Forces’ top unit, he moved to tackle the terrorists. The man in 10B, Satam al-Suqami, moved, too, producing a knife and slitting Lewin’s throat. Less than 30 minutes later, at 8:46 a.m., the plane crashed into the World Trade Center’s North Tower.

Elsewhere, in America and all over the world, people desperate for accurate information turned to the Internet for news. Straining under the overwhelming demand of tens of millions of simultaneous requests, the web’s biggest news sites threatened to collapse. Very few did, thanks in large part to the technology that Lewin himself had developed years earlier: Although only 31 at the time of his murder, he was the co-founder of Akamai, a pioneering technology company whose content routing solutions enable the seamless flow of nearly 20 percent of the web’s traffic.
