Academic and Military Journey

David Norton completed his master’s degree in mechanical engineering from Texas A&M in 1963. He connected with fellow Aggie Joe D. Hoffman, who had since moved on to Purdue University to join what was then called the “Jet Propulsion Center.” Hoffman invited Norton to Purdue for his doctorate work.

“Under Joe Hoffman’s mentorship, I investigated the early bursting of Army rocket-assisted shells,” Norton said. “We constructed a laboratory model to simulate the conditions of rotating rockets with burning propellant. I then spent two years developing a fluid mechanical computer model, which helped explain the ordnance failures we observed.”

Because Hoffman was a new professor, Norton was co-advised by Maurice J. Zucrow himself, who had founded the lab in 1948. Zucrow would retire just two years later, so Norton was one of his last students.

“Joe Hoffman’s guidance was invaluable throughout this period,” Norton said. “He encouraged independent problem-solving and never pressured me for rapid results. He allowed me to achieve success at my own pace.”

David Norton's dissertation, co-written with Joe Hoffman, analyzed the fluid mechanics of rocket motors. Soon after, Dr. Norton would become Captain Norton.

After finishing his Ph.D. in 1968, Norton entered active military service. Out of 90 officers in his class, Norton was one of only three who received a stateside assignment: the Jet Propulsion Lab in California, where he continued his research into rocket nozzle flow.

Norton’s and Hoffman’s careers then followed parallel paths. While Hoffman continued his teaching work at Purdue, Norton accepted a faculty position at Texas A&M. For 16 years he taught courses in air-breathing and rocket propulsion — often utilizing the Gas Dynamics textbooks written by his two co-advisors, Joe Hoffman and Maurice Zucrow. He then spent 14 years at Houston Advanced Research Center (HARC), focusing on in laser, geophysical, and DNA research. He ended his career working for a local school district and running a non-profit to promote K-12 STEM education.

As for Hoffman, he stayed at Purdue for his entire 42-year career. He taught and studied computational fluid dynamics, gas dynamics, and numerical methods. He eventually became director of Purdue’s propulsion lab, and in 1998 led the charge to rename it in honor of his mentor: the Maurice J. Zucrow Laboratories.

Joe Hoffman and David Norton remained friends and academic collaborators for more than 50 years.

The Next Generation

Fast forward to 2026. Zucrow Labs has grown exponentially, now hosting more than 200 graduate students and $21 million in annual research on its 24-acre campus. As the largest propulsion lab in academia, it attracts researchers from all over — people like Jeremy Boyce.

Originally from St. Louis, Boyce loved engineering and science, but didn’t know specifically what he wanted to pursue. While completing his mechanical engineering degree at BYU-Idaho, a professor told him about Purdue University.

“When I found out about Zucrow Labs, I was so impressed by all the work they do out here,” Boyce said. “I flew down here on my own dime and met Dr. Son, and decided I wanted to join his team.”

“Our group here at Zucrow studies advanced energetic materials: explosives, propellants, and pyrotechnics,” said Steve Son, the Alfred J. McAllister Professor of Mechanical Engineering. “We have a propellant team and a detonation team, and Jeremy will be working with our detonation team. We’re very interdisciplinary, so he could be studying post-detonation fireballs, or material science of crystallized explosives.”

“It’s amazing, the amount of thought and research that goes into such a fast reaction,” Boyce said. “We are taking unbridled energy, and making it do what we want in just a split second. That really appeals to me.”

By this point, Boyce had also joined the Army National Guard, advancing to become a field artillery officer. “I have plenty of experience with ordnance,” he said. “But it will be great to work on the science behind those explosions.”

Full Circle

It’s for people like Jeremy that David Norton and his wife Connie (BS HHS 1967) created the Joe D. Hoffman Award: designed to support graduate students studying at Zucrow Labs, especially those with a military background.

“My years at Purdue were formative, providing opportunities that shaped my career,” Norton said. “I am deeply grateful for the education and role models Purdue provided. I hope the Joe D. Hoffman Award will inspire deserving students to achieve their educational goals at Zucrow Labs.”
