David Bruce Montgomery
1938-2026
David Bruce Montgomery was a universally celebrated and loved marketing science scholar. David was an institution builder and a mentor. As a scholar, David’s contributions were prolific and foundational. As an institution builder and a mentor, David’s contributions were deep and sustained.
David secured four degrees from Stanford. His BS in Electrical Engineering in 1960, then his MBA in 1962 followed by MS in Statistical Sciences in 1964 and finally his doctoral degree in Management Science in 1966.
David’s academic professional life of teaching, researching and mentoring was devoted to Stanford for more than 40 years, after very productive five years at MIT Sloan School. David retired from Stanford as The Sebastian S. Kresge Professor of Marketing, Emeritus.
Marketing science as a distinct field study emerged in the 1960s and Dave laid the scholarly foundations for management science in marketing. The contribution came in the form of two books: one, Management Science in Marketing (1969) and the other Stochastic Models of Buying Behavior (1970). It all began with Dave’s doctoral dissertation on Probability Diffusion Models. Dave identified non-stationarity as an important element in the consumer stochastic choice. William (Bill) Massy, the doctoral advisor of Dave and former Vice President at Stanford University, has this laudatory observation, “…non-stationarity allows for the effects of advertising and other environmental drivers. This was an important contribution to the theory. In his dissertation, Dave articulated the model, developed estimators for its parameters, and showed that it did indeed fit the Market Research Corporation of America’s consumer panel data—the most comprehensive (and extensive) consumer behavior data available.”
James M. Lattin, the Robert A. Magowan Professor of Marketing Emeritus, explains how Dave's research insights have become accepted classroom wisdom. “Dave’s research helped us to understand that unless we are careful, we may mistakenly conclude that consumers are changing their behavior, when in fact what we may be seeing is differences in behavior across consumers, who are in fact not changing at all. Current students of marketing all learn this; in that sense, they are standing on the shoulders of Dave and other marketing scientists who have come before them.”
The first book was written by Dave and Glen Urban, David Austin Professor in Marketing Emeritus at MIT Sloan School of Management. Listen to Glen describe the origins of the book and its composition. “In the summer of 1966 Dave and I committed to summer session on “Marketing Models” but soon learned how little material was out there and that it was not organized. This caused us to write Management Science in Marketing – the first textbook on OR, statistics, model building, and computer systems to marketing problems. It was a big project and Dave, and I were a real team. Dave was very insightful and expert in stochastic models while I was more on the simulation and behavioral modeling side. We both learned a lot and hopefully helped others gain entry knowledge on the emerging field of what has grown dramatically in the last 50 years and could now be termed “AI Modeling in Marketing”. One vivid memory was sitting on the floor at Dave’s house in Lincoln Massachusetts and building the index – the finals step in the manuscript creation process. We used 3”x5” index cards laid out reference stacks on topic and names on the floor of his living room. Such was the old technology, but it worked.” How impactful was this book? Seenu Srinivasan, Adams Distinguished Professor of Management Emeritus and a long-time colleague of Dave at Stanford, has this to say, “It provided a summary of the research papers on mathematical models in marketing and their optimization in various areas of marketing such as advertising and salesforce management. My own introduction to quantitative research in marketing was through this book.”
The second book was on Stochastic Choice Models (1970). Listen to Bill William Massy. “I think it was Dave who commented during a session in my Arbuckle annex office, “The three (Bill Massy, Dave Montgomery, Don Morrison) of us have created a critical mass: a scholarly school of thought, so to speak, one of the first in marketing science.” We cemented that by writing a book: Stochastic Models of Buying Behavior [Massy, Montgomery, and Morrison, MIT Press, 1970].” Donald Morrison, one of the founders of Marketing Science and a very distinguished scholar (Professor Emeritus at University of California at Los Angeles), has this recollection, “Dave and I wrote our doctoral dissertations at the same time under Bill Massy. Our dissertations are the foundation for the well-received Massy, Montgomery and Morrison, “Stochastic Models in Marketing”.” Seenu Srinivasan summarizes the contributions of this book this. “The book provides systematic treatment of consumers’ probabilistic choice among brands in a product category. In particular, the book showed how to take customer heterogeneity into account. It also demonstrated that not incorporating heterogeneity can lead to incorrect inferences regarding underlying consumer behavioral processes.”
Russell Winer, Willam Joyce Professor Emeritus at New York University, who graduated from his doctoral program at Carnegie Mellon University in 1977 speaks to the impact of these books on doctoral education. “We had just read the 3M (Massy Montgomery Morrison) book, Stochastic Models of Buyer Behavior, in a doctoral seminar led by Rick Staelin at CMU. I was also familiar with his models’ book with Glen Urban.”
In the subsequent decades, there were many contributions through journal articles.
“David was a prolific scholar,” says George G.C. Parker, the Dean Witter Distinguished Professor of Finance Emeritus. “He just produced a ton of research published in highly rated academic journals.” One of those contributions stands out even more than others. First-mover advantages with Marvin B. Lieberman in Strategic Management Journal (SMJ) in 1998.
Gurumurthy Kalyanaram (GK), a fellow academic who was then in the doctoral program at MIT Sloan School has this recollection of the SMJ paper. “When I was studying the empirical relationship between order of market entry and growth rates and equilibrium market shares during my doctoral days at MIT and subsequently, I found that Dave’s SMJ paper with Lieberman offered the most clear and concise review and synthesis of the interdisciplinary and eclectic extant work (drawn from economics, marketing and strategy) in the area of first-mover advantages.”
Dave was a gifted and phenomenal mentor and institution builder. His reach and impact were broad and deep. Dave was instrumental in building the distinguished and vibrant marketing group at Stanford Business School. Listen to Seenu Srinivasan. “Dave Montgomery was a major force in building the marketing area at Stanford University’s Graduate School of Business. He was the one who recruited me to Stanford. I very much enjoyed working with him in recruiting faculty and building a supportive atmosphere among quantitative and behavioral marketing faculty. He was a generous colleague, always offering thoughtful and sincere words to those around him”.
He contributed to MIT Sloan’s growth in the 1960s, though his tenure there was relatively short. Glen’s book on Management Science in Marketing is a testament to Dave’s collegiality and contributions.
There were so many other institutions that benefited from Dave’s insights and wisdom. Seenu speaks to this, “Dave Montgomery contributed to other academic institutions. He was previously on the faculty at MIT/Sloan during which he spent a year visiting the Indian Institute of Management, Calcutta and contributed to its development. He was the academic director of the Marketing Science Institute from 1995 to 1997. He was the founding dean of the school of management at Singapore Management University from 2003 to 2005 and was a consulting/visiting professor of marketing and management.”
As Seenu observes, “The ever-lasting legacy of David Bruce Montgomery is his role as one of the fathers of the marketing science discipline.” Dave’s contributions to institutionalizing the community of marketing science are fundamental. As Seenu summarizes, “He was one of the founders of The Institute of Management Sciences (TIMS) Marketing College in 1967 and its community of scholars, which in its early years organized a special session at the annual American Marketing Association conference. The Marketing College paved the way for INFORMS (Institute for Operations Research and Management Sciences) Society for Marketing Science (ISMS).”
Dave himself offered this recollection on the birth of marketing science conference and journal. “Dick Wittink received a suggestion from his thesis advisor, Frank Bass, to run a quantitative marketing conference at the Stanford Graduate School of Business.” Dick then discussed this idea with Dave, and they were soon collaborating on co-chairing and developing the conference ultimately named the Marketing Science Conference which took place March 26-28, 1979, at Stanford. The Proceedings were edited by Dave and Dick and were published by the Marketing Science Institute in June 1980. The demand for attending quickly outstripped available classrooms at the Business School and the co-chairs had to arrange to borrow classrooms in the Stanford Law School. It was a good thing that it was scheduled for Spring break, or the conference would have crashed on takeoff for lack of session space.
Dave was also the first departmental editor for marketing for the journal Management Science and was guest editor for the first issue of Management Science dedicated to marketing.
As Gurumurthy Kalyanaram (GK) recollects, “Frank Bass was insistently glowing in his praise of Dave’s inspired leadership in organizing the first marketing science conference and in editing the proceedings of the conference – the proceedings which became the prototype for the marketing science journal.”
Dave was an insightful mentor, always generous and wise. This is what Leigh McAlister, the Ed and Molly Smith Chair at The University of Texas at Austin, has to say of Dave’s organic sense for mentorship. “Dave seemed to me to be running the marketing doctoral program at Stanford when I entered. He gave me a gift that changed the trajectory of my career when he assigned Seenu to work with me on a presentation for the marketing seminar.”
Dave was recognized by the community with many awards. For instance, he received the 2002 American Marketing Association Career Contributions to Marketing Strategy Award. He was a Fellow of INFORMS and an Inaugural Fellow of ISMS.
Dave was – more than anything – was an extraordinary human being. His warm and welcoming disposition, including that smile, is universally acclaimed. He was a wonderful husband and dad. He was a remarkable colleague and friend. The numerous poignant testimonies speak to this repeatedly.
GK: “Dave was always warm to everyone. Always responsive. Always generous. Even if he was doing you a favor, Dave would be thanking you. When I asked him for his reflections on Al Silk, he wrote back, “Thanks to you for making it imperative for me to reflect back on many wonderful professional experiences.” And when I asked him for his reflections on IIM Calcutta for MIT’s South Asian Digital History, he would immediately agree to a conversation though at that point there were many personal exigencies in his life.”
John Roberts, Scientia Professor, University of New South Wales: “Beyond this (scholarship) was Dave's generosity and the large ambit that it spanned. When I taught Global Marketing at the Stanford Graduate School of Management after Dave, he carefully took me through the cases he used, he gave me his insights, and he shared his notes. This help not only enhanced the student experience, but it also taught me much the world that I did not know - it greatly broadened my horizons.”
Russ Winer: “I first met Dave at an ORSA/TIMS conference (the forerunner of Marketing Science conferences) as Dave was a founder of the TIMS College on Marketing (the forerunner of ISMS). This was around 1974. It was a little intimidating to meet one of the "big names," but Dave was extremely nice and very funny. I liked him immediately. Over the years, we met numerous times at conferences and other venues, and it was always a joy to chat. I was involved with MSI when Dave was the Executive Director in the late 1990s. My last major interaction was in Singapore somewhere around 2005 when Dave was the dean of the business school at Singapore Management University. My wife, Toby, met his wife, Toby, and we had a great time together. He wanted me to succeed him at SMU, but it wasn't going to work out with my family situation.”
Don Morrison: “While I have many Academic sons and one First Girl, Barbara Kahn, Dave is my only Academic Brother. Working with the same advisor, doing similar research, we could have been competitors. Nothing could be farther from the truth. We supported each other. We cheered when the other received an award. We wrote letters of recommendation for each other. We had many family gatherings, in NYC, Cambridge and Palo Alto. One memorable gathering was at our small two-bedroom apartment on Riverside Drive in NYC. David and Scott are a little older than our daughters Heather and Michelle. Our girls were so excited to spend time with—as they called them—the “Gomery Boys”.
Glen Urban: “I remember when I first interviewed at MIT in 1966. Dave had just arrived from Stanford, and he was such a welcoming host that I knew we would be lifelong friends. Another giant in our field has moved on and Dave will be fondly remembered.”
Bill Massy: “He always was energetic and very creative…and a very fine man!”
George Parker: “He managed to maintain a dimension of balance in his life that is not always quite so apparent in a lot of high-achieving people.”
Seenu Srinivasan: “Dave and his wife, Toby, were close family friends to me and my wife, Sita. We have visited each other’s homes often. Dave's wife Toby, whom he met at Stanford as an undergraduate, was an attorney. Dave's older son, Dave R.., is a professor of Geography at U. of Washington. His second son, Scott, is a professor of Art History at U. of Denver. Dave's daughter Pam, a schoolteacher, lives near Denver, as does Scott. Dave and Toby have five grandchildren. Dave had a jovial personality and great warmth. I miss him very much. May his soul rest in peace!”
Sarah A. Soule, the Philip H. Knight Professor and Dean at Stanford Graduate School of Business and Morgridge Professor of Organizational Behavior: “Beyond his professional accomplishments, Dave was a supportive and generous colleague, always offering thoughtful and sincere words to those around him. His commitment to his students and to the broader academic community inspired countless people in their pursuits of knowledge and excellence.”
