Leslie E. Robertson, the structural engineer for the World Trade Center, has died at the age of 92, reports Fred A. Bernstein for the New York Times.
Designing the structure of the Towers was a high point of Robertson’s career at the time. The collapses of the Towers during the September 11th terrorist attacks caused him anguish. “My sense of grief and my belief that I could have done better continue to haunt me,” he wrote in his book, The Structure of Design.
Some engineers have argued that a more conventionally structured tower would have fallen sooner than Robertson’s design.
