William Arthur Arendt Jr., known affectionately as Bill, was called home by our Heavenly Father on July 5, 2024, at the age of 79 in Arlington, Texas. Born into this world on the joyous day of December 25, 1944 in Manhattan, New York, Bill was a man of loyalty, integrity, and quiet strength, reserved yet possessing a witty sense of humor that endeared him to many. Bill answered the call to serve his country with honor, dedicating five years to the United States Army, including three tours of duty in Vietnam, followed by service in the Army Reserves. His commitment to service was a hallmark of his character, reflecting the patriotism and courage that defined his generation. Bill’s educational journey began in New York, attending PS 89 and PS 73 in Queens for his primary and middle schooling, followed by graduating in the class of 1962 at Newtown High School. He was a member of the Order of DeMolay and a 3rd degree Mason. He furthered his education at the Pratt Institute School of Architecture, earning an Associates in Applied Science (Building and Construction) and a Bachelor of Science in Construction Management, which laid the foundation for his successful career in architecture. Bill’s career was marked by precision and a quiet excellence that won him the respect and admiration of his colleagues and clients alike. Professionally, Bill had a distinguished career in project management, dedicating over three decades to American Airlines, Inc. From 1977 to 2009, he was instrumental in the development of major corporate facility projects. He served as a Senior Project Manager and Regional Manager, overseeing major projects like the $1.3 billion Terminal 8 Redevelopment Project at JFK International Airport. Bill oversaw the design and construction of the AA Admirals Club at LaGuardia Airport, which was considered one of the premier clubs at the time, and gained much notoriety within the architectural community. He concluded his career at Aguirre Roden as part of the URS Management Team, managing the redevelopment and expansion of the Dallas Love Field Terminal from 2009 to 2013. Beyond his professional life, he found joy and relaxation in his hobbies, which included assembling model airplanes, building intricate train setups, and using his architectural expertise to craft dollhouses for his grandaughters. Bill’s most cherished moments, however, were spent in the company of his granddaughters, sharing in the innocent delight of watching the animated series “Bluey” together, a simple joy that brought him immense happiness. Bill is survived by his loving wife, Linda Arendt; children, Kenneth Arendt, Jessilyn O’Bannon, and Brian Arendt; son-in-law Nolan O’Bannon; grandchildren, Natalie and Elizabeth O’Bannon; brother, Douglas Arendt; and niece and nephew, Dana and Paul Arendt. He was preceded in death by his parents, William A. Arendt Sr. and Elizabeth A. Arendt, and his son, Robert Arendt. Bill’s life was a testament to the enduring values of faith, family, and country. His departure leaves behind a legacy of integrity and devotion that will continue to guide and inspire his family and all who were privileged to know him. He will be deeply missed and forever remembered with fondness and respect. A Celebration of Life will be held on July 24th at 11:00 am at First Methodist Mansfield, located at 777 N Walnut Creek Dr., Mansfield, TX 76063.
