He combined a World War II veteran’s perspective with decades of entrepreneurial and philanthropic activity, becoming a recognizable voice on exponential technology trends.
Biography and Early Life
Raised in Los Angeles, Prell served in the U.S. Army during World War II and experienced captivity as a prisoner of war before liberation. After the war he returned to California, studied psychology at UCLA, and developed a lasting interest in measurement, forecasting, and the emerging field of computing. His Los Angeles roots shaped a career that linked local innovation, university life, and global technology discourse.
Career Highlights

Publications, Talks, and Ideas
Prell was widely associated with clear, historically grounded charts and essays that traced exponential advances in computing and related technologies. His talks often explored the implications of compounding performance (frequently contextualized alongside Moore’s Law), human enhancement, artificial intelligence, and longevity research. He favored empirically reasoned “long-horizon” views, making his slide decks and white papers popular in lecture halls and discussion groups. Archival collections of his correspondence, research notes, and presentation materials are held by UCLA Library Special Collections.
