San Diego’s story is one of innovation, compassion, and vision—and few individuals have embodied that spirit quite like Conrad Prebys. A real estate developer turned transformational philanthropist, Prebys left an indelible mark on the region through bold investments in science, medicine, education, and the arts. His name now graces some of San Diego’s most important institutions, but it’s his values—curiosity, generosity, and belief in the power of people—that continue to shape the future of the city.

From Modest Beginnings to Major Impact
Born in South Bend, Indiana, in 1933, Prebys came from humble beginnings. He eventually made his way to San Diego, where he built a successful career in real estate development. But unlike many in his field, Prebys saw wealth not as a measure of personal achievement but as a resource to be stewarded for the greater good. In the second half of his life, he committed himself almost entirely to philanthropy—donating more than $350 million to causes that advanced medical research, supported education, and brought culture to the community.

A Champion for Cancer Research and Biotech Innovation
Conrad Prebys’ contributions to the field of biomedical research have helped propel San Diego into one of the world’s leading hubs for life sciences. His $100 million gift to the Sanford Burnham Prebys Medical Discovery Institute established one of the top biomedical research centers in the nation, supporting groundbreaking work in cancer, immunity, aging, and rare diseases.

He also made a significant impact at the Salk Institute for Biological Studies, funding critical cancer research that continues to unlock new treatments and therapies. His belief in science as a path to healing continues to ripple through the labs and clinics of San Diego’s vibrant biotech corridor.

A Believer in Education and the Power of the Next Generation
Prebys never forgot the importance of opportunity. He invested heavily in San Diego State University and UC San Diego, funding scholarships, performing arts programs, and student facilities designed to enrich both academic and social experiences.

His gifts weren’t just about bricks and mortar—they were about people. His scholarships continue to support first-generation college students and aspiring professionals who, like him, come from working-class backgrounds with big dreams.

A Lifelong Advocate for the Arts, Animals, and Community
You’ll also find Conrad Prebys’ name at the San Diego Zoo—one of the top zoos in the world—where he supported wildlife conservation and educational outreach. In 2015, the Conrad Prebys Africa Rocks exhibit opened, blending his love for animals with his commitment to education and family-friendly enrichment.

His support extended to The Old Globe Theatre, La Jolla Music Society, and other cultural organizations that make San Diego a thriving center for the arts.

More Than a Donor—A Visionary of Humanity
What made Conrad Prebys different wasn’t just the scale of his giving—it was his thoughtfulness. He gave quietly, often without fanfare, and was known for his deeply personal approach. He believed in investing in people with character, in projects that uplifted the soul, and in institutions that could outlast his own lifetime.

In the words of those who knew him, Prebys gave because he loved people—he loved their potential, their resilience, their spark. He didn’t just build a legacy; he built momentum.

A Legacy That Continues to Shape San Diego
Today, San Diego stands stronger because of Conrad Prebys. His name lives on in buildings, programs, and research initiatives—but more importantly, in the lives of those he touched. From students to scientists, artists to doctors, and families to future leaders, his generosity is a thread running through the fabric of the city.
