Peiffer’s imaginative group biography The Slip: The New York City Street that Changed American Art Forever (2023), published by HarperCollins, immersed its readers in the lives of the group of artists who gathered on the Coenties Slip in Lower Manhattan in the late 1950s and early 1960s – among them Ellsworth Kelly, Robert Indiana, Agnes Martin and James Rosenquist – and in the process conjured a singularly vivid picture of its time and place. The Slip was longlisted for the National Book Award, shortlisted for Apollo’s book of the year and won the New York City Book Award. She co-curated an exhibition based on the book, ‘The Artists of Coenties Slip’, which was on show at MoMA from October 2024–September 2025. As director of content at MoMA since 2023, she has overseen the museum’s content strategy and production on the museum’s website, as well as on YouTube, Spotify and WhatsApp. From 2012–17 Peiffer was senior editor at Artforum and she continues to write for publications including the New York Times and the New York Review of Books.
