Martin L. Leibowitz
1936 – 2026
It is with great sadness that we have to inform you of the passing of Marty Leibowitz. Marty Leibowitz was a founding member of the Q Group as well as committed participant, frequent speaker, Board member, and Fellow. Throughout a career that included leadership positions at Solomon Brothers, TIAA, and Morgan Stanley, he published 10 books and over 200 articles, which garnered numerous Graham and Dodd and Bernstein Fabozzi/Jacobs Levy awards for outstanding articles in the Financial Analyst Journal and Journal of Portfolio Management, respectively. His influence on the field of quantitative finance is hard to overstate, contributing to thinking about securities yields, portfolio risk and management, franchise value, endowment investing, and many other topics. Among his practical contributions, Marty led the digitization of bond values that allowed for real-time analysis of yields and prices. His work to create Treasury STRIPS and his thinking on zero-coupon bonds were the impetus behind the development of bond immunization and dedicated portfolios. In addition to his monumental contributions to scholarship and investment management, Marty was a generous colleague who delighted in interacting with other researchers, learning about their work, and mentoring younger professionals.
