Diana Wagner Obituary

Diana P. Wagner, nee Diana Beth Pietraszewski, 67, passed away on January 15, 2024 after an undoubtedly courageous, many would say heroic, 4+ years long battle with cancer. Her bravery was a hallmark of her character  throughout her entire life, up until her final days. 

Diana was born on April 9, 1956  to Frank and Wanda Pietraszewski in West Hartford, CT. She was the youngest of three children, including a brother, Mark Peters of Fort Pierce, FL, and a sister, Valerie Pietraszewska of West Chesterfield, NH. After graduating from Conard High School, she matriculated to Williams College in Massachusetts, where she studied Economics and French Literature. Diana was admitted to one of the first classes of women at Williams College and was a first generation student. A testament to her ever-enduring tenacity, Diana worked at the Williams Inn while enrolled to pay for her college studies. An avid Francophile, Diana spent her junior year abroad in France, and loved to return whenever she could. 

On the day of her graduation, Diana moved to New York City and landed her first job at Kidder, Peabody & Co., and quickly made her mark as one of the smartest people in any room, a trait which all who knew her would remark upon throughout her life. Also, early on in her career, Diana obtained an MBA from NYU Stern School of Business, which she achieved through many long night classes. Her strength shone through during a time when women faced many challenges in the field, but this kicked off a lifelong career in investment management. Diana spent time at many industry giants, including Lehman Brothers, Credit Suisse First Boston, Morgan Stanley, and most recently, was a Managing Director at J.P. Morgan where she spent 14 years as a Fixed Income Portfolio Manager. Ever pioneering, prior to joining J.P. Morgan, Diana was a founding member of NewMarket Capital, a hedge fund of funds, where she spent 7 years. She was also a CFA Charterholder. 

In 1984, Diana met Edward F. Wagner Jr and they wed in 1989 at St. Thomas More Church in New York City. They had four children: Edward F. Wagner III (1993), John P. Wagner, James F. Wagner, and Caroline E. Wagner (1995). Her bravery was once again evidenced as she was absolutely determined to carry and birth healthy triplets at the age of 39. 

Diana was completely dedicated to her family and kids. Between early morning wake-ups for hockey, nightly bed-time reading, planning trips to places far and wide, ensuring them a robust education, fostering their talents & hobbies, and everything in-between, Diana was determined to raise well-rounded and kind people. Most of all, Diana's love was the ultimate trademark of her as a mother, and as a person. 

When not otherwise occupied, Diana was an avid-animal lover and was forever followed by canine companions. She even allowed one of her kids to bring home four chickens from a class project, which stayed in the family's NYC apartment for a couple weeks! The apartment was graced with all sorts of fauna, be it dogs, hamsters, guinea pigs, fish, frogs, geckos, (and the aforementioned chickens), each of whom she loved.

Diana also had an unquenchable thirst for knowledge, which she satisfied by tearing through books, museum visits, lectures, and travel. She loved to ski, she was a masterful needle-pointer, and had an eye for interior design and architecture. Her favorite place in the world is her home in Bridgehampton, NY, where every piece of furniture or design detail has Diana’s mark on it. She also fell in love with her new-found home in Vero Beach, FL in 2020. Nonetheless, Diana was happiest wherever her family was. 

In every facet of her life, Diana was brave, kind, loving, smart, and generous. She was an avid patron for organizations she cared for, including Queen of the Most Holy Rosary Church located in Bridgehampton, NY and Float Hope Now located in Indian River Shores, FL. Diana also showed her care through service, as she taught confirmation classes at Queen of the Most Holy Rosary, and was a Eucharistic Minister there. She was also a dedicated member of The Williams College Alumni Committee. 

Diana was predeceased by her parents Frank and Wanda Pietraszewski. She is survived by her devoted and loving husband, Edward F. Wagner Jr, and her children, Edward F. Wagner III, John P. Wagner, James F. Wagner, and Caroline E. Wagner. Diana has left an indelible mark on this world and on her family, and was an extraordinary person.
