In his new biography, billionaire entrepreneur Elon Musk revealed that he and his partner, Grimes, have welcomed a new baby.
The baby boy’s name is Techno Mechanicus, or Tau for short. The name Tau has various meanings, including being the 19th letter of the Greek alphabet, the 19th star in a constellation, and a type of unstable subatomic particle.
The exact age of the baby was not disclosed.
Musk, who is the owner of X (formerly known as Twitter) as well as the founder of SpaceX and Tesla, already has two children with Grimes.
Their first child, X Æ A-Xii Musk, was born in May 2020, and their second child, Exa Dark Sideræl Musk, arrived in December 2021 via surrogate.
They are commonly referred to as X and Y, which are also the names of electric cars produced by Musk’s company, Tesla. Musk and Grimes have a somewhat tumultuous relationship and typically announce the arrival of their children a few months after their births.
The biography of Musk, titled “Elon Musk,” was written by American writer and journalist Walter Isaac.
Musk is a father to 11 children, but lost his first-born child from sudden infant death syndrome (SIDS) when he was just 10 weeks old.
He has been married three times, twice to Westworld star Talulah Riley, and once to Canadian author Justine Wilson.
