From a Washington Post obit by Fred A. Bernstein headlined “A. Eugene Kohn, whose architecture firm reached for the sky, dies at 92”:

A. Eugene Kohn, whose powers of persuasion helped build Kohn Pedersen Fox, the New York-based architecture firm he founded in 1976, into a global powerhouse responsible for buildings in 45 countries, including four of the 10 tallest buildings in the world, died at his home in Montecito, Calif.

As president of the firm, widely known as KPF, Mr. Kohn focused on establishing and managing relationships with clients. In a 1986 profile, Paul Goldberger, then the architecture critic for the New York Times, described Mr. Kohn as one of the most effective salesmen in the architecture business.
