John Dutton Conant Little of Lincoln passed away peacefully on September 27, 2024, at age 96. John was an Institute Professor at the Massachusetts Institute of Technology and Professor of Management Science in the MIT Sloan School. He retired in 2017 after a distinguished career spanning seven decades, making fundamental contributions to operations research and marketing science. Along the way, he touched the lives of hundreds of faculty and staff and thousands of graduate and undergraduate students from all over the world. In operations research, he is best known for Little’s Law, his generalized proof of the widely applicable queuing formula (L = λW), published in 1961.
John was born in Boston and grew up in Andover, Mass. At MIT, he majored in physics and edited MIT’s VooDoo magazine, “MIT’s only intentionally humorous publication.” Working at General Electric after graduation, he met his future wife, Elizabeth Alden; they both entered graduate school at MIT in 1951. Elizabeth received her Ph.D. from MIT in 1954 in physics, and John obtained his Ph.D. from MIT in 1955 in physics and the emerging field of Operations Research where he was the first doctoral student.
After serving two years in the U.S. Army, John taught at Case Institute of Technology and then rejoined MIT in the Sloan School in 1962 as an associate professor of operations research and Management. In 1967, he co-founded Management Decision Systems, Inc. (MDS), a marketing models software company with clients such as Nabisco, Coca-Cola, and Ocean Spray.
John has been director of the MIT Operations Research Center and, within the Sloan School, head of the management science area and the behavioral and policy sciences area. He was a past president of both the Operations Research Society of America (ORSA) and the Institute of Management Sciences (TIMS) and, following their merger, became the first president of the succeeding society, INFORMS. He was elected to the National Academy of Engineering in 1989.
John traveled for work all over the world and jogged or biked everyday no matter where he was, rain or shine. He enjoyed gathering his own seafood, especially with family, be it fishing, clamming, musseling, hunting for whelks, or jigging for squid. In the mid-1970s, he received his “master squid chef certificate” from the National Marine Fisheries Service. He famously invited Sloan students and faculty from overseas to his Thanksgiving dinners, which included a walk at the Old North Bridge in Concord beforehand and a square dance in Lincoln after. He kept working, and kept up with new technology, new discoveries, and new applications, including being able to summon an Uber for the trip to his office, into his early 90s.
John, predeceased by his wife Elizabeth and his two sisters, Margaret and Francis, leaves four children (Jack, Sarah, Thomas, and Ruel), eight grandchildren, and two great-grandchildren.
The family is deeply grateful for the group of aides who provided continuous, expert, and loving care for John in the last stages of his life’s journey.
A memorial service in celebration of John’s life will be held on Saturday, Nov. 16, 2024 at 1 p.m. in First Parish, 4 Bedford Road, Lincoln. A private graveside service for family will be held at Lincoln Cemetery.
John was a great supporter of women in science both in his professional community and within his own family. He encouraged, supported, advised, and helped facilitate their careers at every stage. He also was a great supporter of the arts, having long-running subscriptions to the Boston Symphony and the American Repertory Theater. He always bought tickets for four so that he and Elizabeth could invite friends, colleagues, and/or family to every show he attended. After Elizabeth passed away, he continued to buy his four tickets and fill his usual seats with a wide variety of enthusiastic guests.
The family invites you to share a favorite memory with us on John’s tribute wall, post a photo, a video, whatever you may feel moved to write or share, or simply “light a candle.” Cards and letters may be sent to the Little Family, c/o Dee Funeral Home, 27 Bedford St., Concord, MA 01742.
For those who wish to make a donation in memory of John and would like a suggested organization, we offer the Science Club for Girls and the American Repertory Theater. Arrangements are entrusted to Dee Funeral Home & Cremation Service of Concord, which provided this obituary.
