Nancy Groves Manning passed away on May 11, 2023. She was predeceased by her beloved husband Winton Howard Manning in 2004.  Born on December 29, 1934, in St. Louis, Missouri, she was the daughter of Clara Mercedes Groves and George Breckenridge Groves. Although an only child, Nancy grew up in with a large extended family in a multi-generational home with her grandparents, Clara and Albert Groves; her mother; an aunt and uncle, Phyllis and Walter Heimbuecher; and cousins, Judy Heimbuecher Habighorst and Gail Heimbuecher Hamilton. She attended John Burroughs School in Ladue, graduating in 1952. Nancy had a great talent for drama, and dreamt of becoming an actor. She pursued acting while in college, and starred in many roles, including Shakespeare's Lady Macbeth. Nancy earned her undergraduate degree from Washington University in 1956. She later earned her doctorate in psychology from the same institution.

While taking graduate classes in psychology, she met a handsome young teaching assistant, Winton H. Manning, whom she married in 1959. The newlywed couple moved to Fort Worth, Texas, as Win had accepted a teaching position at Texas Christian University. There Nancy became absorbed in starting a family and entertaining their faculty friends. In 1965 the family moved to Haworth, New Jersey, in order for Win to join the staff of the College Board in New York City. While living in Haworth, with the encouragement of her thesis advisor and support of her dear husband, Nancy was finally able to turn her sights to completing her dissertation.  She earned her doctorate in psychology in 1967. The family then moved to Princeton in 1968 in order for Win to join Educational Testing Service.

Nancy had a 40-year career as a licensed clinical psychologist. She completed a postdoctoral training program in family therapy at the Philadelphia Child Guidance Clinic of the University of Pennsylvania Hospital. In Princeton, she served as consulting psychologist and Clinical Director of the Northeast Career Center and therapist and Clinical Director of Trinity Counseling Service. She co-founded Princeton Psychological Associates with four colleagues in 1980.  A skilled psychotherapist, she mentored many developing professionals as a field supervisor for doctoral candidates in psychology at Rutgers University. She was always passionate about helping her patients live happier, more fulfilled lives.

Following her retirement from practice as a psychologist, Nancy embarked on a new adventure by enrolling in the docent training program of the Princeton University Art Museum. As a docent she especially enjoyed researching individual works of art in the collection for gallery talks, and working with school children from Trenton. She was a member of the Present Day Club and the Nassau Club of Princeton. She belonged to All Saints' (Episcopal) Church for 55 years.  As a resident of Stonebridge in Montgomery, she enjoyed her French conversation group, play and poetry reading groups, helping in the library, and serving as a member of the welcomers committee. Nancy was an accomplished home chef, enjoyed traveling the world with her late husband, and cherished and celebrated her children and grandchildren.

She is survived by her son Winton H. (Tony) Manning, III; daughter, Cecelia M. Tazelaar; son-in-law, Eric G. Tazelaar; three granddaughters, Julia B. Tazelaar (married to Joseph M. Wells), Sophia M. Tazelaar, and Clara J. Tazelaar.
