Home » World-Renowned Structural Engineer Les Robertson, ENR's Man of the Year in 1989, Dies
Leslie E. Robertson, preeminent structural engineer and ENR’s Man of the Year in 1989, died on Feb. 11—one day before his 93rd birthday. The cause was cancer.
Robertson was world-renowned as an innovator not only for supertall structures but for all structures. “Les was a perfect architect's engineer,” says L.C. (Sandi) Pei, a partner in PEI Architects, who worked with Robertson on myriad buildings, many designed by his late father, I.M. Pei.
