Just five months after their destruction on 9/11, this extraordinary program brought together Leslie E. Robertson, structural engineer of the Twin Towers, and builder John Tishman, who headed the construction management of the project. As had been planned the summer before 9/11, their joint lecture described the innovative design and unprecedented challenges of building the World Trade Center. Leslie Robertson spoke not only about the original design of the towers, but also discussed issues of the airplanes' impact and showed and commented on photographs he took at Ground Zero in the days and weeks after 9/11.
