Civil engineer Roman P. Wengler was a “disruptor” in the world of dam building long before that was a word for an innovator.
Wengler, who died in Houston on Aug. 8 at 95, was a global leader in the design of thin-arch concrete dams, a 39-year veteran of Harza Engineering Co., at the time, one of the top 10 dam designers worldwide. He rose to be chief engineer and was a member of the Harza board of directors before he retired in 1993.
