He was born in Panna Maria, Texas, to Walter and Lucy Zaiontz. Claude married Laurie on October 28, 1950, and together they shared 72 years of marriage. He devoted his life to his family and was a loving and generous man who quietly supported many charitable organizations throughout his life.
While raising eight children, Claude founded The Zee Company, Inc., building it into a respected FAA certified aircraft component repair station serving customers throughout the world. Later, he founded ZEE Systems, Inc., manufacturing FAA-approved environmental control, heating, and air conditioning systems for numerous aircraft platforms. Claude was among the first jet engine mechanics in the United States Air Force. His exceptional technical ability, analytical thinking, and innovative approach led to many practical and cost-saving solutions for complex aviation challenges. His work and leadership left a lasting impact on both the aviation industry and the many employees and customers whose lives he touched.
Claude was a devout Catholic whose faith guided his life. He enjoyed hunting and fishing, and his time spent with family and friends at the deer lease created countless cherished memories. In later years, he especially enjoyed deep-sea fishing from his boat. Those who knew Claude will remember his quiet generosity, unwavering work ethic, dry sense of humor, and willingness to help others. He will be deeply missed by all who had the privilege of knowing him.
