Mary Catherine Barton Wintermantel was born on January 26, 1928 in Dade County near Lamar in southwest Missouri. Her parents were Mary Wylma Harned and Virgil Avery Barton. When Catherine was about 5 years old, her family moved to Warren County, Iowa. She attended Squaw Valley Country School and later attended Indianola High School. During high school she stayed at Bierma's boarding house during the week as there was no transportation available for students who lived in the country at that time. After graduation in 1945, Catherine attended Simpson College in Indianola, Iowa, where she pledged Alpha Chi Omega sorority. During college, she worked part-time for Dr. Lester Hooper in Indianola. When Dr. Hooper became ill, he asked Catherine to help him keep his office open, and she took time off from college to help him. She graduated from Simpson College in 1951 with a degree in Sociology. \r\n\r\nCatherine had considered a career in the medical field, and Dr. Hooper recommended she consider a new profession at that time, Cytotechnology, which involved the study of cells to detect cancer in a new test at the time called the pap smear. She graduated from the first cytotechnology class in the state of Iowa and began working at Clinical Pathology Laboratory in Des Moines. The laboratory developed a cytotechnology school which Catherine taught for many years. She was very involved in the Iowa Society of Cytology and was president of the society at least twice. In the mid-1980s she changed career paths and began working for the Iowa Department of Agriculture as a microbiologist until her retirement in 1990. \r\n\r\nCatherine married Myron Jacob (Mike) Wintermantel in 1963. She and Mike met at Simpson College but had their first date many years later on Groundhog Day, 1963; it was a blind double date for another couple that Mike had set up, and he needed a date for himself. That couple never went out again, but Cathy and Mike were married in November of the same year. They had two children and worked hard to make sure their children had every opportunity to explore and learn about the world, always encouraging and supporting them. Catherine visited all of the continental United States and enjoyed two trips to Europe. She continued to travel to visit her children, who lived out of state, until the pandemic limited travel last year. While working full time, she was always involved in her children's lives, and among many things served as a Cub Scout leader, Camp Fire leader, and Sunday School teacher at different times. She participated in many organizations throughout her life including, among others, PEO, Alpha Chi Omega Alumni, Chi Delta Phi, The Des Moines Metro Opera Guild, and United Methodist Women. \r\n\r\nCatherine was compassionate, kind, and embraced life with great joy. She loved nature from the flowers around her house to the the wildlife in her backyard and was known to call family and talk while watching animals out her window or from her back steps. She touched the lives of all those she met and will be missed by many. Catherine is survived by her son, Bill (wife Ann) Wintermantel of Salinas, California, her daughter, Mary (husband Achih) Chen of Mercer Island, Washington, grandsons Michael Wintermantel, Bryan Wintermantel, Jacob Chen, and granddaughter, Madison Chen. She was preceeded in death by her husband, Mike Wintermantel.
