Jerome S. Stefanko, 86, a cherished husband, father and grandfather died peacefully Jan. 23, 2025, at his home in Zionsville. Born in Pittsburgh, he lived a life rich with purpose, creativity and love.

A 1956 graduate of North Catholic High School, he continued his education at the University of Dayton, where he earned a bachelor’s degree in physics in 1960. It was during his time in Washington, D.C., he met the love of his life, Mary Lou (Luartes) Stefanko, with whom he shared 63 beautiful years of marriage. Together, they built a life filled with laughter and adventure, starting in Bethel Park before eventually settling in Zionsville, where he completed his distinguished career.

His professional journey began at Allis Chalmers, being one of the earlier nuclear physicists forging nuclear energy. From there he went to the former Westinghouse, where he contributed to the groundbreaking NERVA (Nuclear Energy Rocket Vehicle Application) at Large, Pa. After 12 years in nearby Bethel Park, the family moved to Zionsville where he dedicated the last 20 years of his career to PP&L, serving as the manager of nuclear fuels for the Susquehanna Steam Electric Station with unwavering commitment and expertise.

Beyond his professional achievements, he was a true Renaissance man with a passion for the arts. He was a skilled artisan woodworker, crafting exquisite furniture and restoring pieces with meticulous care and attention to detail. He also wrote poetry and short stories, sharing them with family, friends and the community. He also delighted in music, playing the guitar and showcasing his remarkable voice as the lead vocalist in a three-person combo during his younger years.

In addition to his wife, he is survived by his sons, Jerome Jr. and John and his wife, Lori; daughter, Karen Moffett and her husband, Paul; grandchildren, Erin, Matthew, Ellen, Michael and Annie.
