Eustachius John "Jack" Pysar, age 87, of Anderson, SC, passed away on Thursday, October 30, 2025, at Rainey Hospice House.

Born January 26, 1938, in New Britain, CT, Jack was the son of the late Rev. Eustachius Stanley Pysar and Mae Chupron Pysar.

Jack was a proud veteran of the United States Army and was stationed in Japan. He received his B.S. from Clemson University and later received an additional B.S. and M.B.A at the Rochester Institute of Technology. Jack was a Vice President of Crown Cork and Seal in Philadelphia. He had a strong work ethic and a deep love for his family. Jack was an avid Clemson Tiger fan and never missed a Clemson sporting event. He collected trains, stamps, coins and books, and loved classical music and tending to his yard. He was a student of history, especially of WWII. Some of Jack's favorite times were spent traveling with his beloved wife Maryanne. He was a member of St. Joseph Catholic Church. Above all else, Jack was a wonderful man who loved his family deeply. He will be missed beyond measure.

Jack is survived by his loving wife of 57 years, Maryanne Demling Pysar; daughters, Elizabeth Pysar (Thomas Hansen) and Kathryn Christiansen (Jason); sister, Barbara Arvia; and grandchildren, Jackson, Margaret, and Casey.

A private family service will be held at a later date.
