Bobby “Bob” Crupper

April 21, 1948 — July 11, 2022

Hulbert, Oklahoma

A great man passed today into the loving arms of his Lord Jesus Christ. Bobby Joe Crupper left his earthly home at 7:35 am, Monday, July 11, 2022. We will grieve and miss him every day, but we are comforted to know that he has joined his family who passed before, and they are praising the name of the Lord in Heavenly Glory.

Bobby Joe (Bob) Crupper was born in Fort Madison, Iowa, on April 21st, 1948, to Floyd and Juanita Crupper, the youngest of 6 children.  He was a rascal growing up, mischievous and funny, but he was blessed with the structure of a loving family and God-fearing father and mother, who taught him to value himself and his family, as well as hard work and persistence against all odds.

He attended Dallas City High School and was a star on the basketball team.  He also won the Iowa Golden Gloves boxing championship tournament for his weight class in 1967.

In 1964, he met the love of his life, Ruth Ann Vancil, and they married July 15, 1965.  They had two beautiful children and they raised them to love the Lord and to love their family.

Bob loved his family above all else, and worked hard every day to ensure that they were well looked after.  He and his bride Ruth made sure that no matter how hard times may have been, their family never wanted for anything, and that they would succeed and prosper in this hard old world.

In 1978, the family moved to Oklahoma. God’s Country. That’s what he called it. Bob and Ruth made a home in Nowata, Oklahoma, the place where Bob’s ancestors helped settle the state in the early 1900s.  Bob started his company Bob’s Well Service there, and he and Ruthie were loved and respected as pillars of the community and strong supporters of their children’s activities in Nowata High School, including coaching summer softball, and playing an instrumental part in the funding of the new fieldhouse for the football stadium in 1982.

Bob and Ruth built several businesses in the oil and gas industry between 1980 and 1993, moving to California for a few years to be closer to their children, and eventually returning to God’s Country when they purchased their home in Hulbert, Oklahoma. In 1994, Bob began his long-haul trucking contractor business, retiring in 2016.  He drove over 3 million miles on the roads of our country and never had an accident, receiving several driving and safety awards.

Bob is preceded in passing by his father and mother Floyd and Juanita Crupper, sister Dorothy and her husband Harold Gallaher, sister Mary and her husband Jerry Logan, sister Francis Mixer, brother Charles (Chuck) Crupper, father-in-law Chuck Vancil, and mother-in-law Mary Pollack.

He is survived by his wife Ruth Ann Crupper of the home; son Robert Crupper and fiancé Korena Lilly-Graffeo, Tulsa, Oklahoma; daughter Lori Siburt and her husband Joe, Cambridge, Ohio; grandchildren Cameron and Nora Jones-Crupper, Sapulpa, Oklahoma; US Army SPC Joseph Siburt, Fort Drum, New York; and Emily and John Crum, Caldwell, Ohio; sister Vera and her husband Jim Brown, Fort Madison, Iowa; brother-in-law Mervin Mixer, Fort Madison, Iowa; sister-in-law Francis Crupper, Ivesdale, Illinois; mother-in-law, Sandra Vancil, Lomax, Illinois; as well asmany loving cousins, nieces, nephews; other family members and friends.
