Elon Musk's firstborn son, Nevada, passed away at 10 weeks old in 2002
Elon Musk's firstborn son, Nevada Alexander Musk, passed away at just 10 weeks old in 2002. Nevada was born to Musk and his then-wife, Canadian author Justine Wilson, in 2002. Sadly, he died from sudden infant death syndrome (SIDS). In a 2010 essay for Marie Claire, Wilson recounted the tragic incident:
> Nevada went down for a nap, placed on his back as always, and stopped breathing. By the time the paramedics resuscitated him, he had been deprived of oxygen for so long that he was brain-dead. He spent three days on life support in a hospital in Orange County before we made the decision to take him off it. I held him in my arms when he died.
Wilson also revealed that she and Musk coped with Nevada's death by planning to get pregnant again as soon as possible. As a result, they welcomed twins, Griffin and Vivian, in April 2004, just two years after Nevada's passing.
It is important to note that there is a discrepancy in who held Nevada when he passed away. While Musk claimed on Twitter that his "firstborn child died in my arms," Wilson disputed this, stating that she was the one holding Nevada when he took his last breath.
