JEFFERY ALAN HANNEMAN, age 68, of Twinsburg, Ohio, passed away on January 13, 2026, from complications of ALS. He was a cherished husband, father, grandfather, and brother.

Born to the late Alice Louise (Moore) and Frederick J. Hanneman, Jeff grew up in Brecksville, Ohio. He was a devoted husband, celebrating 46 years of marriage with his beloved wife Pamela (Frantisak), also from Brecksville. They were both the youngest of six children in their families.

Together, they built a family founded on love, laughter, and respect. Jeff was a proud father to his sons and daughters, Gregory (Alan Vangpat), Christina Rowan (Ben), Katherine Schreiber (Kurtis), and Andrew (Channing). He was an adoring "Pop-Pop" to Abigail, Killian, Luke, Nora, Kase, and Ava. His grandchildren were the light of his life, and he cherished every moment spent with them.

Jeff was a fond brother to Judy Rataj (Woody, deceased), Steve (Judy), Mike (deceased, Carol), Sherry Collins (Darrell, deceased), and twin sister Jennie Remington (Bruce). He had 22 nieces and nephews.

Jeff's professional life was marked by a 42-year long and dedicated career at Allen-Bradley, which became Rockwell Automation. His colleagues knew him as a reliable and hardworking individual who brought warmth and a sense of humor to the workplace. He held multiple roles over his long career, receiving patents and numerous awards until his retirement in 2021.

He greatly loved and adored his wife Pam, also his best friend. Jeff had so much fun getting dressed up to go dancing, visit wineries, or dine out with her. He was very interested in genealogy and family history, collecting data and visiting historical sites across Ohio and Pennsylvania. He also loved hiking in the metroparks with his family. Jeff enjoyed watching the Cleveland Guardians and Browns, and later in life he liked to watch PGA golf on television.
