Grant Imahara, cohost of the wildly popular TV show Mythbusters, died on Monday at the age of 49, according to a report from the Hollywood Reporter. The cause of death was reportedly a sudden brain aneurysm.
Trained in electrical engineering, Imahara worked at George Lucas’s Industrial Light and Magic during the 1990s and 2000s, building robots for the Star Wars prequels. Imahara also led the team handling animatronics for movies like A.I. Artificial Intelligence, Galaxy Quest, and the Matrix sequels, among plenty of other classic sci-fi films.
But it was his roles on the Discovery Channel’s Mythbusters and Netflix’s White Rabbit Project that would win Imahara worldwide recognition as an enthusiastic and joyful presence in the world of technology. The outpouring of grief over Imahara’s death on social media was immediate, with both somber friends and grateful viewers sharing stories of how much he meant to them.
