David A. Quadrini, Sr. (October 8, 1939 - August 27, 2022) David A. Quadrini, Sr. died Saturday, August 27. Born in Rochester, New York, as the third of six children of Pierina and Attilio Quadrini, who had immigrated from Italy in 1931. David's strong Catholic faith guided his life from an early age until his last breath. David married Rosemary (Falbo) in 1964 in Utica, New York. Family and faith were paramount to them. They raised four children and were blessed with seven grandchildren. He loved being a father, an uncle, and an active granddad. Rosemary and David were founding members of All Saints Catholic Church, where he was a long-time member and past President of the All Saints Men's Club. David volunteered on many committees and programs at All Saints; especially for the Building Committee when it came time for the church to design and build their current sanctuary and Fellowship Hall. In 1957, David graduated high school from The Aquinas Institute of Rochester where he not only played varsity football, but also played saxophone in the band during halftime. David joined the United States Marine Corps and trained in Aviation Electronics Navigation (ATN). His commanding officer saw David's potential and arranged for him to continue his studies at Rochester Institute of Technology (RIT) where he graduated with Mechanical and Electric Engineering degrees. David and four fellow scientists from Xerox started Triaid Sciences, one of the first environmental-solutions companies focusing on Air, Water, and Land. They developed technologies to fix environmental degradation, which led to David speaking in New York City at the inaugural Earth Day in 1970. In 1976 David moved his wife and children to Texas to design a system to remove environmental toxins from water destined for the Trinity River. For over 20 years with Texas Instruments, David managed design and construction of wafer-fab plants around the world and became Corporate Fire Marshal supporting world-wide manufacturing plants. In the mid 80's David guided T.I. in developing cogeneration, a revolutionary system that produces electricity from the heat generated from chip production. Cogeneration led to his 2022 patent to produce power from desalinating water. David was an independent consultant for years, serving as Chairman for both the National Fire Protection Association (NFPA318), and with the City of Dallas Fire Department Code Committee. His parents and brother, Art, and goddaughter, Carolyn preceded him in death. His wife Rosemary survives him along with four children: Anne (Charlie) Rogers, David Jr., Karen (Evan) Powell, and Susan (Jeffrey) Roddy; seven grandchildren: Thomas and Brian (Anne) Rogers, Samuel (Karen) Powell, and Hannah (Juan), Isabella, Rosemary and Michael (Susan) Roddy; and brother Richard, sister Mary DeCiantis, and sister-in-law Pat Quadrini. A celebration of his life will be held on Wednesday, September 7, 2022 at All Saints Catholic Church in Dallas, Texas at 11:00 A.M. Located at 5231 Meadowcreek Drive, Dallas, Texas 75248.
