In the recently published “Marguerita Mergentime: American Textiles, Modern Ideas,” Virginia Bayer, granddaughter of Mergentime, Linda Florio, graphic designer, and Donna Ghelerter, textile historian, explore Mergentime’s life and career, reintroducing her ideas on modern design, informal dining, and joyful living. The authors are joined by Matilda McQuaid, Deputy Curatorial Director & Head of Textiles, for a conversation on Mergentime’s innovative work for Radio City Music Hall, the 1939 World’s Fair, and New York City department stores.
