Alison Ellen Isenberg

Alison Ellen Isenberg, 63, resident of Princeton NJ and beloved, inspiring, creative, award-winning professor of History at Princeton University, passed away on October 23, 2025. Private funeral services were held at the Princeton Cemetery.

Born June 16, 1962 in West Hartford, CT to architect Marian Ellenbogen Isenberg and businessman Leon E. Isenberg, Alison graduated from the Loomis Chaffee School in 1980 and Yale University in 1984 where she majored in History. Her early work and academic interests laid the foundation of a lifelong commitment to studying cities and writing about the changing, often contentious, dynamics of urban life. Alison's senior thesis, guided by Ann Fabian and supervised by William Cronon, focused on a New England woman, Fanny Cheever, who made a new life for herself in gold rush era San Francisco.

Before graduate studies, Alison worked in urban planning in the NYC Dept of Parks and Recreation and in low-income housing development for the Community Preservation Corporation in the Bronx. In 1995, she completed a Ph.D. in History at the University of Pennsylvania. Her award-winning dissertation on the rise, fall, and transformation of downtowns across the U.S. was written under the mentorship of Michael Katz. The dissertation won the John Reps Award from the Society for City and Regional Planning History (SACRPH), an organization dedicated to promoting the cross-disciplinary study of cities over time and bridging the gap between academic scholarship and the practice of planning. During her graduate years, Alison served a short stint as historian for the Historic American Building Survey of the National Parks Service deepening her knowledge and interest in cities, design, historic preservation, and urban/regional affairs.

In a 30-year scholarly and teaching career that spanned multiple universities, Alison had a vast impact on students and colleagues, on urban history scholarship, and in the wider profession. At Florida International University (1994-97), University of North Carolina at Chapel Hill (1997-2001), Rutgers University (2001-10), and Princeton University (2010-2025), Alison became widely known for astutely mentoring students, building innovative programs in urban history and urban studies, maintaining a rigorous research ethic, writing acclaimed books, becoming a leader in the field, and exhibiting grace and a winning smile through it all. In 2024, she was recognized with an award at Princeton for graduate mentoring which celebrated her teaching expertise, sharp questions. big picture insights guiding a growing number of mentees, and always "going the extra mile" in nurturing the intellectual, professional, and personal growth of students.

Throughout her career, Alison received scholarly and teaching accolades, awards, and honors with grace and characteristic modesty. Her first book, Downtown America: A History of the Place and the People Who Made It (2004) received the Ellis Hawley Prize from the Organization of American Historians, the Lewis Mumford Prize from SACRPH, and several other honors spanning humanities and historic preservation. From 2009-11, Alison led SACRPH as its President. Alison's second book Designing San Francisco: Art, Land, and Urban Renewal in the City by the Bay (2017) received awards in architecture and urban planning, and for pioneering insights in landscape studies. The wide interdisciplinary recognition for Alison's work reflected the breadth and capaciousness of the questions she explored, as well as her creative use of archives, novel sources, and fresh analytical frameworks.

In 2021, a National Endowment for the Humanities award for work on her next book, Uprisings, recognized the new project's pathbreaking promise. The book is an extensively researched epic story of the life and death of Harlan "Bruce" Joseph, a young man in Trenton, New Jersey who was shot by a police officer in the volatile weeks after the assassination of Martin Luther King Jr, at a time when more than forty people died in what was called the Holy Week uprisings, or King riots. Uprisings, a trenchant study of Mr. Joseph, the circumstances of his death, and his continuing legacy, will be published by Princeton University Press. Alison also collaborated on a feature-length documentary film on Harlan Joseph and his times, and she proudly began collaborations aiming to create a new Harlan Joseph Peace Park in Trenton.

Alison created and led transformative initiatives in urban affairs and the public humanities spanning multiple institutions. In 2013, she became founding, co-principal investigator of the $4.1 million, multidisciplinary Princeton-Mellon Initiative in Architecture, Urbanism, and the Humanities at Princeton University (2013-25), a project that catalyzed research, conferences, postdoctoral scholarship, and new courses on the built environment and "cities on the edge." More recently, she co-led the $1.8 million Robert Wood Johnson "Truth and Repair" project (2023-25), partnering Princeton, Rutgers, and St. Peter's Universities, with cultural institutions across New Jersey to build community partnerships and produce, preserve, and share new scholarship on the impact of structural racism on health and wellbeing of marginalized communities in the state.

Under the umbrella of her Trenton Project, Alison collaborated with playwrights and documentary filmmakers on community-based design, filmmaking, and engaged collaborations in the city. Work across institutions was a hallmark of Alison's remarkable career, and she remained committed to innovative and dynamic place-making initiatives that fostered public participation and enhanced student learning. Alison's skilled navigation of historical archives also involved creating new sources to make the past more directly accessible. In a recent achievement, Alison located and initiated the acquisition by the Princeton University library of over 60,000 Trenton Times newspaper photographs. The trove makes fully accessible to students and scholars the visual heritage of the region. As Alison explained, "by accessing a city through the photographic record, you just ask different questions. You see different things."

Alison's teaching was skillful, engaging, and always visually compelling; her knowledge of U.S. history was capacious. Alison taught immigration history, business history, the history of university design, suburban history, youth in the sixties, urban policy research, documentary film and the city, and the history of urban unrest. Students remember Alison for her generosity, encouragement, and wise advice, as well as for her joy, grace, compassion, and nurturing of creativity and curiosity. Alison took special delight introducing students to the wonders of archival research and nurturing a passion for new insights and excellence in her students. Testimonials to Alison from students, colleagues, and friends speak of the deep, lasting impact of her brilliant example. Alison took enormous satisfaction and pride in her students and postdoctoral fellows – in their growth, careers, and professional accomplishments.

Alison was welcoming, devoted, and loving to her family, network of friends, and beloved students. She was funny, lighthearted, and saw humor in small details of daily life. She had a boundless capacity to listen and always gave measured, forward-looking guidance. She is remembered as a supreme connector, regularly introducing students, friends, colleagues, and family, and always nurturing growth and fellowship. The light she shined on the world by her example is deeply missed.

Alison was a devoted gardener and an avid and vigorous walker, hobbies that reflected how she lived her life. As a loved one noted, "No matter the path we were traveling personally, she'd accompany us, asking questions with curiosity that would beautifully and unassuminglly impact our direction forward." As for her wonderful gardening, her home was filled with plants. "She would move them around the house – with intentionality and grace until she found just the right place that they would thrive. She helped cultivate growth in those she loved in the same deliberate and modest way."

Alison Isenberg is survived by her husband Keith Wailoo of Princeton, a loving partner of forty-one years and fellow historian. Alison and Keith met in college in 1984, married in Miami, Florida in 1995, loved each other abidingly, worked alongside one another for decades, and enjoyed each other's company immensely. Alison is also survived by devoted and loving daughters Sahara Iman Wailoo of Detroit and Myla Eleanor Isenberg Wailoo of Brooklyn. She is survived by mother- and father-in-law, Lynette and Vibert Wailoo of Maplewood, NJ; brother- and sister-in-law, Christopher and Alisa Wailoo of Philadelphia and her nephews Anthony and Andrew Wailoo; cousins Caroline Flaxman, Gary Flaxman, and Laura Flaxman and her husband Kenneth Purser, and their children Ava and Aziza Purser; and brother, Neil Isenberg and his spouse Nicole Gartland, and her nieces Nathalie and Naomi Isenberg.

The Wailoo-Isenberg family asks that contributions in Alison's honor be made to the Rescue Mission of Trenton, one of the many organizations she supported over the years.

A public memorial and celebration of Alison Isenberg will be held at the Princeton University Chapel on Saturday, December 6, 2025 at 11am.

Funeral arrangements are by Orland's Ewing Memorial Chapel.
