Mary Kloss

1949 - 2025

Mary Kloss passed abruptly following a long illness on August 23, 2025. Mary was born in Knoxville, TN, in 1949. She is predeceased by her adoptive parents Florence and Edmund and is survived by her adopted brother Joe (Christina), her nephew Ian (Gibson), and several cousins. Mary attended Bristol Tennessee High School where she was active in student affairs and was a member and officer in the state champion Tennessee High Band. A graduate of the University of Tennessee with a degree in Secretarial Administration, Mary was recommended for her first job by UT faculty and moved to Washington, DC, to work for US Senator Howard Baker representing the State of Tennessee. Following over eight years with the Senator, Mary moved to Houston, TX, to work for fellow senate staffer Robert Mosbacher Jr.. There Mary was able to enjoy many loving friends and family members who lived in the area. During their years in Houston, Mary became godmother to Rob's son and joined Rob in the creation of a society band called "Midlife Crisis." Mary and her friend Sallie Ann were the back-up singers: "The Hot Flashes." Among the band's many highlights were two gubernatorial inaugurations of George W. Bush in Texas followed by two presidential inaugural "Black Tie and Boots" balls in Washington, DC. They also played for the first inaugural celebration for Barack Obama. Mary returned to Washington in 2005 to continue working with Robert Mosbacher Jr. after President Bush appointed him President and CEO of the Overseas Private Investment Corporation. At the time of her death, Mary and Rob had worked together for 47 years. Mary wore a nearly perpetual smile and everyone who knew her can relate stories of her kindness, generosity, and ready sense of humor. Mary was equally effusive in her love of animals, especially her succession of cats. The Blessing of the Animals was her favorite festival day in the church year at St. John's Episcopal Church where she was a devoted parishioner. Mary was an enthusiastic supporter of many local and international child and animal welfare programs throughout her adult life. In her memory, donations may be made to any child or animal welfare program of one's choice. A memorial celebration is planned for 2026 in East Tennessee.
