Early Sunday morning, November 1, Martin “Marty” William Siebert passed away at the age of 95 after a brief illness.
Marty was born on August 26, 1931, in St. Louis and grew up in Webster Groves, Missouri. It was there, while in the fifth grade at Holy Redeemer Catholic School, that he met his future wife on the school playground. He also attended Chaminade Academy and St. Louis University High School. His mother, along with a summer job at a garden nursery, instilled in him a passion for flowers and gardening that stayed with him throughout his long and active life.
He studied business at the University of Missouri and was very involved in his fraternity, Kappa Sigma, serving as president during his senior year. An introductory geology class in college led to his lifelong passion for rock collecting. Upon graduation, he enlisted in the U.S. Army, was stationed at Fort Lewis, near Mt. Rainier, Washington, and served for two years during the Korean War. He graduated from military Morse Code school in California and was training to head a combat communications center.
When he returned home from the service, he married his childhood sweetheart, Mary Anne Voshardt, on April 27, 1957. His career as Regional Manager for Dun & Bradstreet took them to Denver for seven years, where his rock collecting hobby flourished. This was followed by a move back to Webster Groves and then to Houston.
He loved his three children deeply and manifested that by taking them on camping, rock hunting, canoeing, and hiking adventures, serving as Scoutmaster, making creative Halloween costumes, always having a “dad joke” at the ready, and in so, so many other ways. Marty and Mary retired in Huntsville, Alabama, to be close to family.
Once fully retired and in Huntsville, Marty threw his considerable energy and enthusiasm into new, volunteer careers. He oversaw the facilities and grounds for Good Shepherd Catholic Church for three decades and dedicated himself to beautification of the grounds and gardens. He was closely involved in the planning and construction of both the Religious Education Building and the Family Life Center at Good Shepherd. He was also a founding Brother Knight of the Knights of Columbus Council 11672 and served as treasurer for many years. He continued his service as a Scoutmaster, sponsoring several Eagle Scout projects in Huntsville.
The living history program at Burritt on the Mountain was just getting started up in the early 1990s and both Marty and Mary immediately volunteered there as well. Marty worked closely with curator Charlie Pautler to build the living history village on the grounds. This included historical restoration of the cabins and building split rail fences, all by hand, and using traditional tools and techniques. He also took on the role of first-person interpreter of Dr. Burritt, performing at numerous historic Maple Hill Cemetery Stroll events.
He was the greatly beloved “Uncle Marty” to his growing family in Huntsville: from walking his niece, Margie, up the aisle at her 1991 wedding, to attending his great-grandnephew’s 6th birthday party last month, with innumerable family projects, events, and dinners in between.
He was preceded in death by his wife, Mary, his loving mother, Kathleen Mary (McAtee) Siebert, his older brother, Theodore August Siebert, his son, William Owen Siebert, and his nephew Theodore August Siebert, Jr.
He is survived by his daughter, Kathleen Siebert Medicus and son-in-law, Gustav F. Medicus; his son, John Martin Siebert and daughter-in-law, Cody L. Siebert; three grandchildren, Ella Maria Medicus, Amelia Helena Medicus, and Zachary Owen Siebert; four nieces, Mary Margaret “Margie” Zoladz, Maureen Helen O’Donnell, Susan Clair (Siebert) Hughes, and Sandra (Siebert) Burton; his beloved nephew-in-law, Thomas Francis Zoladz; six grandnieces, four grandnephews, six great-grandnieces, and four great-grandnephews.
Visitation will be from 9 to 11 a.m. Friday, November 20, 2026, at Good Shepherd Catholic Church, Huntsville, Alabama with a Mass of Christian Burial at 11 a.m. Inurnment will be held immediately afterward in the Columbarium, followed by a lunch reception in the Parish Hall.
In lieu of flowers, the family suggests donations in Marty’s memory be made to the Good Shepherd Catholic Parish Future Needs Memorial Fund at: https://secure.myvanco.com/L-ZGSQ/campaign/C-14KZQ
