Wyatt Alva Stewart III

Wyatt A. Stewart, III, passed away peacefully on July 21, 2026. Born in Corinth, MS, on August 14, 1939, to Alpha Peck Kinzie and Wyatt A. Stewart, II, he grew up in Memphis, TN, alongside his mother and sister.

Wyatt graduated from Central High School in 1957 before enlisting in the U.S. Navy. Serving as a torpedoman on the SS 336 Capitaine, he embarked on a goodwill tour that took him from San Diego to Japan, Hong Kong, and Australia. By the time of his honorable discharge in 1960, he had earned five promotions, achieving the rank of Second Class Petty Officer (E-5).

Upon returning to civilian life, he attended Memphis State University, where he joined the Pi Kappa Alpha fraternity and graduated in 1964. He later earned a Master’s degree in Social Work from The Ohio State University in 1966 and remained a proud, lifelong Buckeye, rarely missing an opportunity to attend a football game with his son.

Wyatt’s professional life was defined by his expertise in fundraising and political consulting. He served as the Director of Finance and Administration for the National Republican Congressional Committee from 1975 to 1978. That same year, he launched his own firm, Wyatt Stewart and Associates, Inc., which he operated until 2010. Over those decades, he played a pivotal role in fundraising efforts, including programs to elect Congressional Republicans, the Gerald R. Ford New Leadership Committee, the Reagan-Bush Presidential Campaign of 1984, and refurbishing the Statue of Liberty. He was also a dedicated participant in local Washington, DC politics, serving as a delegate to several National Republican Conventions.

Outside of his professional career, Wyatt was a man of varied and passionate interests. He loved his family and valued time spent supporting their passions. Inspired by his wife, Renee, and daughter, Margaret, both avid equestrians, he became involved in the equestrian community. He spent many a weekend ringside supporting Renee and Margaret at horse shows up and down the coast. He also served as President of the Washington International Horse Show and on the Board of Directors and Executive Committee of the U.S. Equestrian Team.

Wyatt was a man who loved sports, especially baseball, and nothing brought him greater joy than cheering on his son, whether during his Little League days, high school years at Landon School, or his college years playing baseball for the University of Richmond and the Bethesda Big Train. Wyatt and Renee rarely missed an opportunity to watch their son play and travelled the country on weekends to be in the stands on game day. They lovingly named their dog slider in honor of Wyatt IV’s signature pitch.

He was also a dedicated supporter of the arts, a passion inspired by his mother who was a concert pianist. Wyatt served as Chairman of the Development Committee for the Washington Symphony Orchestra and was a longtime supporter of the Washington International Piano Arts Organization.

He is survived by his children, Margaret Stewart Nagle and Wyatt A. Stewart, IV; his son-in-law, Paul Nagle; his daughter-in-law, Ryan Lee Stewart; his two granddaughters: Anna Stewart Nagle and Lee Robert Stewart; his step-granddaughter Agnes Nagle; his grandson Wyatt A. Stewart V, named in his honor. He is also survived by his half-sister, Amy Jo Moore (David); and his nephews, Stewart and

Joel Moore, and niece, Katie Jenkins Moore. He was preceded in death by his sisters, Ann Arrington Stewart and Betty Jane Stewart; and his beloved wife of 54 years, Renee Bonynge Stewart.

A visitation for Wyatt will be held Thursday, August 6th, 2026 from 4-7 pm at Joseph Gawler’s Sons, 5130 Wisconsin Ave NW, Washington, DC 20016. A funeral service will occur at 11:15 am on Friday August 7th, 2026, Joseph Gawler’s Sons, followed by a procession to and burial at Congressional Cemetery with military honors. In lieu of flowers, the family suggests donations in his memory be made to the Bethesda Big Train or Washington Symphony Orchestra.
