Biography by Family Those that knew Karl were well-acquainted with his big smile, hearty laugh, ever-giving spirit, one or two short stories, and hardworking attitude that never took shortcuts. He possessed a sharp mind that could recite everything from the mile marker for Sheldon, IA and the Cyclones' starting lineup for the 1972 Liberty Bowl to intimate stories about friends and loved ones. He loved the Lord, his friends and family, serving those around him, and life's simple pleasures. After an interesting nine-year journey through Iowa State University, he ventured out to Montana with his wife Barbara, where he helped establish and manage a restaurant by the name of Karl Mark's Pizza (he had a sense of humor). They lived and made a life together in several midwestern states and eventually settled in Cedar Falls, IA. It is here that they raised their two boys, Matthew and David. Karl was actively involved in church, Boy Scouts, political committees, various hobbies, and volunteering. In December of 2008, Karl was diagnosed with Acute Myeloid Leukemia. He faced his battle with cancer with the same attitude that, in his days of political volunteering, earned him the nickname "Killer Karl." This fierce determination was complemented by his gentle heart which sought to touch the lives of those around him every step of the way. During the four years of his fight, he was sustained by the faithfulness of his Lord Jesus Christ, his unrelenting spirit, "Team Gilbertson," and the prayers of hundreds of friends he made throughout his life.
