Andrew Thornburg

It is with deep sorrow that we announce the passing of Andrew Thornburg, a man of boundless curiosity, adventure, and intelligence. Andrew was born on September 21, 1990 and transitioned from this life on January 19, 2026. In his 35 years, he touched many lives with his wisdom, humor, and unwavering spirit of perseverance.

Driven by an endless thirst for knowledge, Andrew was a lifelong learner and a devoted (unofficial) teacher. He had a passion for discovery and was steadfast in his pursuit of truth. His smile and laugh were unforgettable. Always humble, grateful, and generous, he found joy in meaningful conversations and traveling, and he found strength through music.

Andrew proudly joined the U.S. Marine Corps after high school, serving for a short time but carrying with him a lasting sense of accomplishment. He was finishing his second year of college, earning a place on the Dean’s List both years, with the goal of becoming a Civil Rights Attorney. These achievements are just a few examples of his ability to overcome challenges with courage and fortitude.

He will be deeply missed and forever remembered.

He is survived by his loving wife, Tiah, and his service dog, Tuna, along with many other relatives and friends. We extend our heartfelt sympathies to all who mourn Andrew’s departure. He was preceded in death by his mother, Kimberly.

.....................................

A Celebration of Life in remembrance of Andrew will be held on Saturday, April 11, from 5:00–8:00 p.m. at Pour Bros (event room) in Moline, IL. We invite all who knew and loved him to join us in honoring his memory. Please let us know if you can attend, as food will be provided. You may contact Cortney at 309.644.1412.

Andrew was laid to rest in February at Pikes Peak National Cemetery in Colorado Springs.

In lieu of flowers, we encourage you to honor Andrew’s legacy of learning and teaching by seeking out new knowledge, pushing beyond the boundaries of the known, and sharing those insights with others. We believe this would be the most meaningful tribute to his remarkable life.

If you have the opportunity, we also invite you to explore the website Andrew created a few months ago, which he hoped to share with everyone. https://halos.space/login
