Donald B. Prell (born July 7, 1924, Los Angeles, United States) was an American venture capitalist, author, and futurist known for his long-view analyses of technological progress, his early support of information and computing ventures in Southern California, and his enduring ties to UCLA. 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
- Venture Capital: Principal and founder of a Los Angeles–based venture capital practice (commonly referenced as Union Ventures), backing early-stage technology and information-processing companies during formative decades for the region’s tech ecosystem.
- Entrepreneurship and Advising: Held leadership or advisory roles with a range of startups and civic organizations; mentored founders and supported technology community-building in Southern California.
- Philanthropy and Academia: Longstanding supporter of UCLA initiatives; engaged in programs that preserved historical materials and advanced public understanding of technology.
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.
News and Media Coverage
- 2000s–2010s: Interviews and lectures at universities and technology forums highlighted his historical datasets and technology forecasts; local media occasionally profiled his perspectives on computing’s trajectory.
- 2020: Obituaries and memorial tributes in Los Angeles–area press and UCLA-affiliated publications marked his passing and summarized his contributions as a veteran, investor, and futurist.
- Post-2020 references: Articles and conference talks discussing the history of computing sometimes cite or reproduce versions of his long-view charts.
Social Media and Web Presence
Prell did not maintain an active personal presence on mainstream social media platforms. His digital footprint is primarily institutional: event pages, archived interviews, PDF slide decks, and library finding aids. Mentions also appear in alumni communications and program notes from lecture series and community technology forums.
Recent Projects and Legacy
In his final decade, Prell concentrated on public lectures, refining historical timelines of technological change, and ensuring that his papers would be preserved.
