Sam Shelton, founding director of the Strategic Energy Institute (SEI), longtime professor in the George W. Woodruff School of Mechanical Engineering, and designer of the torch for the 1996 Atlanta Olympic Games, passed away on June 20, 2026. 

Colleagues and friends remember Shelton as a dedicated mentor, collaborator, and educator, whose curiosity, generosity, and sense of humor left a lasting impression on students and peers.

“Sam exemplified the very best of Georgia Tech, and his legacy will continue to inspire generations of engineers and educators,” said Tim Lieuwen, executive vice president for Research at Georgia Tech. “I am deeply grateful for his friendship, mentorship, and leadership. My heartfelt condolences go to his family, and to the many students, colleagues, and friends whose lives he touched.”

A nationally recognized leader in energy systems, Shelton founded SEI as an interdisciplinary organization that brought together engineers, researchers, policy experts, and industry leaders to advance high-impact energy solutions. That vision remains central to SEI’s mission and continues to guide its work today.

“Sam was the quintessential engineer and innovator, whose vision was always accompanied by the development and demonstration of actual products instead of leaving them as promising concepts,” said Srinivas Garimella, Hightower Chair in the College of Engineering and professor in the George W. Woodruff School of Mechanical Engineering. “He had the rare ability to see through nebulous ideas and claims and get to the fundamental engineering truths. I am fortunate to have had the opportunity to seek his advice, which he freely gave. I will miss his friendship and counsel very much.”

During a career of more than 35 years, Shelton made lasting contributions to sustainable energy and engineering innovation. His work spanned combustion research, solar energy technologies, and offshore wind systems. He secured more than $30 million in research funding, held eight patents, founded two energy-focused companies, and helped translate research into real-world energy solutions.

In addition to his research, Shelton was deeply committed to education. During his academic career, he developed undergraduate and graduate courses in energy technology, teaching both in person and online. His Energy 101 course reached tens of thousands of learners through a massive open online course platform, covering topics such as energy supply, independence, economics, and society’s energy demands.

“When I first started at SEI in 2016, Sam and I would meet for lunch to discuss the latest research, consider how far we've come since the Carter administration, and grapple over the world’s energy problems,” said Rich Simmons, SEI’s director of Research and Studies. “Sam was genuine and objective, not working backward from a preconceived notion, but working forward with an open mind to understand, appreciate, and apply the first and second law. He was also colorful and witty! We are all privileged to pay these lessons forward to future energy students.” 

Beyond academia, Shelton’s engineering expertise reached a global stage as the designer of the Olympic torch for the 1996 Atlanta Games, an enduring symbol of innovation recognized worldwide. “The Olympics represented world peace, mankind coming together, and overcoming adversity. It was an amazing event to think about, to witness, to live through, and be a part of helping to create it,” Shelton said in a 2016 interview.

Shelton is survived by his daughters, Suzie and Stacy, three granddaughters, and a wide network of students, colleagues, and collaborators. His legacy continues through the programs he built, partnerships he fostered, and the people he helped.

A memorial service celebrating Shelton’s life will be held Aug. 1 at 1 p.m. at The 57th Fighter Group Restaurant in Atlanta. The family asks that, in lieu of flowers, memorial gifts be directed to Roll Call, Georgia Tech’s Fund for Excellence. Donations may be made at gtalumni.org/SamShelton.
