Born in Chicago, Jacob was raised by Leonard and Nancy Fishman (nee Becker). At New Trier West High School he met his future wife Petrie, and at the University of Arizona he earned a bachelor’s degree in electrical engineering. Jacob and Petrie were married in 1977, and together they founded Lightwriters Neon.
As a father and community member Jacob radiated kindness, dedication to craftsmanship, and the importance of friendship. In the neon world he was a beloved teacher and was known for bridging the gap between being an artist and an engineer. Among his many achievements, co-authoring The Neon Engineers Notebook and teaching countless students over his 50 years in the craft are among what made him a pillar in the community.
Jacob loved photography and playing guitar and percussion in bands with Petrie and friends. He was also known for his HAM radio enthusiasm and served as president of the Northshore Radio Club where he brought people together in his hometown and across the world. More than anything Jacob will be remembered for his sociable nature and always having a joke at the ready.
He leaves behind his wife Petrie; children Arlo, Zoelle, and Molly; grandchildren Eliot, Laila, and L.J. He is preceded in death by parents Leonard and Nancy, and siblings Cyd and Eliot.
