Dr. Robert Hubbard, who made major advances in motorsports safety with the invention of the HANS device, died Tuesday.

Hubbard’s passing was announced on the HANS website, which read: “Our thoughts and prayers go to his family and friends. Bob’s invention truly changed the world of auto racing safety and he was a kind-hearted person who would help anyone in need. He will be missed greatly.”

Hubbard’s Head and Neck Support (HANS) system was a breakthrough in minimizing the risk of whip-like head and neck movement in the event of a crash. Hubbard, a professor of biomechanical engineering at Michigan State University, developed the safety restraint after discussions with Jim Downing, his brother-in-law and an accomplished sports-car racer.

“Dr. Robert Hubbard’s contribution to NASCAR safety remains unrivaled,” NASCAR Senior Director of Safety Engineering John Patalak said to NASCAR.com. “In helping develop the HANS device, Hubbard sparked a safety evolution that continues to this day. His ground-breaking work has elevated driver safety to unprecedented levels. NASCAR extends its deepest condolences to the friends and family of Dr. Hubbard, a giant in motorsports safety.”
