Elon Musk.

Elon Reeve Musk (born 1971) is a South African-born American entrepreneur, engineer, and investor who has emerged in the early twenty-first century as one of the most consequential, controversial, and genuinely unprecedented figures in the history of technology and business, simultaneously leading more major enterprises than any comparably prominent executive in modern history. His best-known companies are Tesla, including the Optimus humanoid robot program, and SpaceX, which encompasses the Starlink communications satellite system, but Musk also runs Neuralink pursuing brain-computer interface technology, the Boring Company developing tunnel transportation, and xAI, founded in 2023 to compete with OpenAI — having additionally co-founded PayPal and OpenAI, from both of which he later departed. Elon Musk (Simon and Schuster, 2023) by Walter Isaacson — Professor of History at Tulane University, former CEO of the Aspen Institute, former chairman of CNN, former editor of Time, and the celebrated author of biographies of Steve Jobs, Albert Einstein, Benjamin Franklin, Leonardo da Vinci, and Jennifer Doudna — is a 688-page account based on two years of direct access to Musk and interviews with 129 individuals, placing it squarely within Isaacson's established tradition of intensive authorized biography.
