Terence Riley, a curator, author, critic and tireless promoter of new architecture, who helped two major museums through significant building projects, died Tuesday, May 18 in Miami at age 66, apparently of an underlying heart condition. As Chief Curator of Architecture and Design at the Museum of Modern Art (1992 to 2006), he helped the institution execute Yoshio Taniguchi’s $850 million renovation. Then, as director of the Perez Art Museum Miami (2006 to 2009), he oversaw the design of its acclaimed new building by Herzog & de Meuron. Riley was also a practicing architect whose partnership with John Keenen in the firm K/R lasted from 1984 until his death. He lived in a house that he designed with John Bennett, which was based on the work of Ludwig Mies van der Rohe, in Miami’s Design District.
