Jeff built a successful career as a creative director at an advertising agency. In his personal life, he loved working on his home in New Jersey. He was an avid golfer, a devoted Penn State football fan, and most importantly a grandfather who treasured every moment with his grandchildren.
Beloved husband of 55 years to Carol Knauff. Devoted father of Kathleen Adams, her husband Kenneth Adams, Christine Knauff and her husband Brian LeVine. Cherished grandfather of Jerey, Makenzie, Elsie and Lily. Dear brother of Kay DePaolo. Also survived by his loving dog Misty, and many nieces and nephews.
