George H. Seaberg, 88, of Riverdale, Iowa, passed away Wednesday, January 28, 2026, at Jersey Ridge Place, Bettendorf, Iowa.

Services to celebrate George’s life are tentatively planned for Spring and will be announced in the near future. George’s body was donated to the University of Iowa Deeded Body Program and burial will take place with his wife at Moline Memorial Park at a later date. Trimble Funeral Home & Crematory, Moline, is entrusted with arrangements. Memorials may be made to University of Iowa Sports Medicine.

George Howard Seaberg was born January 13, 1938, in Moline, the son of Reuben Winfield and Pearl Olive (Kruse) Seaberg.

In 1956, George graduated from Moline High School, where he was a standout basketball player. He continued his basketball career on scholarship at the University of Iowa. He was a member of Phi Gamma Delta fraternity and graduated with a degree in Industrial Engineering. While at Iowa, he met an Alpha Xi Delta sorority girl named Margaret “Sue” Trissel, and the rest is history. The couple married on August 29, 1961, and started a life together that spanned over 64 years until Sue’s passing on September 18, 2025.

Also in 1961, George joined the U.S. Army, serving proudly for two years as a helicopter pilot. After his service was complete in 1963, George and Sue moved to Fostoria and later Sandusky, Ohio, working as an engineer for Union Carbide and Pillsbury.

George went to work for Ralph Hahn & Associates in Springfield, Illinois, and while living there, he designed and built the family home that is still standing today. The family’s final move was back to the Quad Cities, where they resided for over 54 years in Riverdale, Iowa. In 1973, George fulfilled a lifelong dream and started a business out of his home, ARI Industries. When the company moved to Moline, it was renamed Seaberg Industries. The company later moved to the Rock Island Industrial Park.

A Davenport satellite shipping and warehousing facility was opened in 2005. Two years later, these activities were combined with laser metal cutting in Rock Island about a mile from the main building.  In 2007, a group of five managers bought Seaberg Industries.

George was a man of strong faith, forging many friendships and bonds at several different Lutheran churches over the years, including Trinity Lutheran Church in Moline, where he was raised, and later Holy Cross Lutheran and Redeemer Lutheran Church, both in Davenport, and most recently Our Savior Lutheran Church in Bettendorf.

George belonged to Bettendorf Rotary, the Full Gospel Businessmen’s Association, and was able to find a way to merge two of his passions, his faith and staying fit, by founding the Champions Fitness Bible Study, which is still in existence today. He kept in great shape over the years by running, working out at the gym, and even dabbling in ultimate fighting in his 70’s. While in memory care, he could be seen walking around the hallways for exercise frequently.

George enjoyed golfing, skiing, and remained very loyal to the University of Iowa. He remained connected to the University of Iowa over the years, serving on the board for the College of Engineering and helping to build the catwalk at Carver-Hawkeye Arena.

He also volunteered to those in need. After going to Florida to help with the Hurricane Andrew relief efforts, he was motivated to help get Habitat for Humanity started here in the Quad Cities.

Above all else, family was the most important thing to George. He was a supportive father to his three children, always finding time to support them in their various sports and other activities. He and Sue enjoyed traveling in retirement, taking several memorable international trips together. They were also proud grandparents, and were lucky to be able to take each of their grandchildren on a trip of their choosing when they turned 10, a tradition that created priceless memories for them all.

George is survived by his three children and their spouses, Thomas and Ann Seaberg of Davenport, Sue Seaberg Sampson and Bryan Sampson of Bettendorf, and Anne and Ken Atkinson of Hillsville, Virginia; seven grandchildren, Joshua (Jessica) Seaberg, Nathanael (Amanda) Seaberg, Raena (Lucas) Nerhus, James (Priscilla) Sampson, Michael (Quinn) Sampson, Talia Sampson, and Evan (Clare) Atkinson; five great-grandchildren, Graham, Harrison, Parker and Elliot Nerhus, and Gabriel Sampson; and his brother and sister-in-law, Bill and Ida Seaberg. He was preceded in death by his beloved wife of over 64 years, Sue Seaberg; his parents; and siblings, Dick (Wanda) Seaberg and JoAnne (Dave) Lund.
