“As one of the few to follow in the footsteps of Philip Johnson at the Museum of Modern Art, Terence Riley has had an important platform in the world of architecture and design over the last 14 years. He helped raise awareness of foreign architects like Rem Koolhaas, Kazuyo Sejima and Herzog & de Meuron in the United States. He made architecture shows a high-profile staple of the museum’s exhibition program. He served on the juries of several major architecture projects and on countless panels discussing architecture. And he was instrumental in the creation of the new Modern, the redesigned building by Yoshio Taniguchi that opened last year. Now someone else will fill Mr. Riley’s shoes; he announced on Thursday that he would step down as the museum’s chief curator of architecture and design in March.”
