Art Gensler, who built one of the world’s largest architecture firms, dies at 85

M. Arthur Gensler Jr., who grew his three-person design business into one of the world’s largest architecture firms — designing airport terminals, mega-skyscrapers and office interiors that aimed to make the workplace more pleasant and productive — died May 10 at his home in Mill Valley, Calif. He was 85.

The cause was complications from lung disease, said Kimberly Beals, a spokeswoman for his namesake firm, Gensler.
