Grant Imahara has passed away at the age of 49.
The host of Discovery’s MythBusters and Netflix’s White Rabbit Project “died suddenly following a brain aneurysm,” according to The Hollywood Reporter. “We are heartbroken to hear this sad news about Grant,” a rep for Discovery told the outlet Monday evening. “He was an important part of our Discovery family and a really wonderful man. Our thoughts and prayers go out to his family.”
Imahara, an electrical engineer, joined MythBusters in 2005 during the show’s third season. He went on to host over 200 episodes of the series. In 2016, Imahara joined Netflix’s White Rabbit Project with fellow co-hosts Kari Byron and Tory Belleci.
As news of Imahara’s death emerged overnight, many of his friends and former colleagues took to social media to mourn his passing.
“Heartbroken and in shock tonight,” Byron tweeted. “We were just talking on the phone. This isn’t real.”
