Jack Robertson Obituary
Jack Thomas Robertson, 93, of Bozeman, Montana, passed away peacefully on November 4, 2025, surrounded by loved ones.
Jack was born on September 22, 1932, in Henderson, North Carolina, to Herman Ross Robertson and Myrtle Oneida (Riggan) Robertson. A proud Eagle Scout and graduate of Henderson High School (Class of 1952), Jack carried his strong sense of discipline, curiosity, and adventure throughout his life.
After high school, Jack enlisted in the United States Air Force, serving from April 11, 1951, to April 10, 1955, where he was stationed at Arlington Hall, Virginia. It was during this time that he began his long and distinguished career as a cryptanalyst with the National Security Agency, a position he held until his retirement in 1976.
On December 21, 1957, Jack married the love of his life, Lois May Cordle, at Bruen Chapel Methodist Church in Merrifield, Virginia. Together they built a life full of adventures of traveling and camping in almost every state - while living in Virginia, Maryland, Alaska, Pennsylvania, and finally settling in Bozeman, Montana, where they have resided since 1979.
After retiring from federal service, Jack started his own general contracting business in Shrewsbury, Pennsylvania, where he took pride in building two custom homes. Following the Three Mile Island nuclear incident, Jack's lifelong love of the mountains inspired a move west. In the spring of 1979, he and his childhood best friend, Jack Harper, drove cross-country in his brand-new Ford Bronco which he was so proud of, ultimately choosing Bozeman as the perfect place to call home. Jack Harper fell in love with Montana as well, and moved his family out here just a few weeks later.
An avid outdoorsman, Jack found his greatest joy in the wilderness. Whether fishing, hiking, hunting, snowmobiling, or gopher hunting, he lived for the adventure. His favorite spots - Taylors Fork, Carrot Basin, and Lightning Lake - became the backdrop of countless stories and memories. He would go on 3-week adventures at a time- sometimes with those who dared to keep up or just by himself.
One of his proudest achievements was catching the Montana State Record Golden Trout in June 1989, a moment that has been memorialized on his basement wall ever since.
His love of the outdoors started while stationed in Alaska where he would have a bush plane drop him and a couple of coworkers off in the remote wilderness to go camping, fishing, and hiking and then proceed to tell the pilot to pick them up in the same spot one week from now and at an exact time; and Jack would be there waiting for the pilot.
Jack always loved taking his grandson Alex on his many outdoor adventures passing these passions onto Alex as well...including gardening. Jack was passionate gardener, known for his abundant sweet corn and famously large "Early Girl" tomatoes. His love of the land extended to photography, where he had a gift for capturing light and landscape in breathtaking detail.
Later in life, Jack and Lois shared a passion for genealogy, tracing their family roots as far back as the 1400s.
Jack is survived by his beloved wife of 67 years, Lois; his children, Cynthia (Cindy) A. Granot and her husband Paul J. (PJ) Granot Jr., and Stuart L. Robertson and his wife Rocio; grandchildren Haley DeVries (fiancé Cameron Mott) and great-granddaughter Ava Mott, Alex DeVries (wife Trista), Ashley Anna Robertson and Sara Martinez , Emma (Robertson) Hamberger (husband Joshua) and great-granddaughters Tayli and Mara Hamberger. He is also survived by his brother, Brice Eugene Robertson of The Villages, Florida, and his lifelong friends Jack Harper of Bozeman and Thurston Faulkner of Maryland - friendships spanning more than 75 years.
A private graveside service will be held in December to honor and celebrate Jack's life. In lieu of flowers, the family requests donations be made to the NRA or Citizens for Balanced Use, organizations that reflect Jack's love of the outdoors and his enduring values.
The family extends heartfelt gratitude to The VA, Cornerstone Caregiving, and Stillwater Hospice of Bozeman for their compassionate care during the final months of Jack's life.
