“In Process” was a series of conversations with creative professionals I presented over the course of a year at Soho House and Dumbo House in New York City. Its goal was to offer insight into the creative process of individuals working in a wide range of disciplines.This installment of the series featured Michelle Elligott, MoMA’s Chief of Archives, Library and Research Collections, who discussed René d’Harnoncourt and the Art of Installation, her 2018 book on René d’Harnoncourt, the legendary director of MoMA from 1949 to 1968. His working methods as a curator included elaborate sketches—now considered to be artworks in their own right—of objects and installations from landmark exhibitions he presented at the museum, and a number of these sketches were shown in conjunction with our conversation.
