Chuck Tagg was born in Mitchell, South Dakota on June 28, 1932 to Lawrence and Lenora Tagg. He was the youngest of 5 children. The others were: Larry, Bill, Helen, and Stan. His father was a Methodist minister, and Chuck grew up in a variety of small towns in the Midwest, mostly in Illinois.

Chuck graduated high school in Pana, Illinois. He studied mathematics at the University of Illinois at Champaign-Urbana for a couple of years, then was drafted into the Army in 1952. He served 2 years, mostly as a chaplain's assistant at a basic training camp.

In 1955, Chuck married Leah Mae Truxell, making her forever a Mae Tagg. They were married for 54 years, until her passing in 2009. They had two children: David and Brian. David passed away from Leukemia at age 2.

Chuck and his family moved to California in 1961 so he could take a job as a mathematician at Hughes Aircraft Company, in Fullerton. His initial job was to do calculations for the engineers, but then he found the computers. He learned computer programming by reading the manuals, and quickly became the resident expert in programming and related activities. For several years he taught after-hours technical classes on programming topics. He retired from Hughes Aircraft in 1988, after 27 years with the company.

Chuck enjoyed growing plants. His interests here included landscaping, growing a vegetable garden, and growing orchids, bromeliads, ferns and especially begonias. He was an active member of the American Begonia Society, where he shared knowledge with others, judged begonias in shows, and was president of the American Begonia Society for a time.

Chuck enjoyed camping and rockhounding. In the summer, the family would go camping in the mountains. At Easter, the family would spend the week in the desert camping, exploring and rockhounding. Closer to home, he and the family also enjoyed gem and mineral shows.

Chuck and Mae went on a Marriage Encounter weekend in the 1970s and became active in the Marriage Encounter community. They were leaders in bringing United Methodist Marriage Encounter to Southern California. They traveled to learn how to put together and present a Marriage Encounter weekend. They then brought their knowledge back and used it to prepare other couples to help present weekends. They presented 50 weekends over many years before "retiring" from Marriage Encounter.

With Mae, Chuck was active in the United Methodist Church in a variety of capacities. At one time or another they were part of landscape committee, sang in the choir, led bible study, participated in stewardship and financial affairs, acted as lay speakers during worship and more.

Chuck is survived by son Brian, daughter-in-law Sheri, grandchildren Nicholas, Christopher, Joshua and Hannah, and great-grandchildren Eli and Keira. He will be missed, but we have certainly not "lost" him. Chuck Tagg lives on in us – not only in our memories, but in the ways that he influenced us and helped to shape our lives.
