Before Bernie Marcus co-founded the home improvement giant Home Depot, which now boasts a market value of $343 billion, he harbored a different ambition: to become a doctor. That dream was derailed when his family could not afford medical school, prompting him to enroll in pharmacy school at Rutgers University. Even then, Marcus often skipped classes to sell Amana freezers door-to-door, as recounted in a Home Depot-published memoir, but he still earned his degree. After graduating, he climbed the corporate ladder at various manufacturing firms until a pivotal moment in 1978: he was fired from a now-defunct hardware store called Handy Dan. That setback spurred him to reinvent himself, and he co-founded Home Depot alongside Arthur Blank. Marcus died in November 2024 at age 95, with an estimated net worth of $11 billion.

Now, his philanthropic legacy is paying tribute to his original passion for medicine. The Marcus Foundation, which Bernie and his wife Billi established in 1989, has awarded $28.7 million to Dr. Chuck Murry, director of the University of Southern California's Stem Cell Center. The funds will support clinical trials exploring stem cell-based therapies designed to regenerate tissue damaged by heart attacks. "Murry and his team have advanced gene-edited cellular therapy to the point that the time is right to support cells as living medicine in this new form of treatment," said Jonathan Simons, chief science officer of the Marcus Foundation, in a statement.

This gift represents the largest single donation the foundation has ever made to USC and one of its most significant contributions to academic medicine. It follows a pattern of targeted giving. In 2024, the foundation donated $25.9 million for stroke research at Emory University School of Medicine and Grady Health System's Marcus Stroke and Neuroscience Center. In 2019, it gave $20 million to establish a Department of Integrative Medicine and Nutritional Sciences at Jefferson's Sidney Kimmel Medical College.

Since its founding, the Marcus Foundation has granted more than $2.7 billion through over 3,500 grants, covering medical research, Jewish causes, free enterprise, veterans, and children's welfare. Medicine has always been a central focus. The foundation describes itself as a leading U.S. philanthropist in biomedical research, concentrating on five key areas: stem cell research and regenerative medicine, earlier cancer detection and treatment, autism diagnosis and treatment, integrative medicine, and cardiovascular disease—including stroke.

The foundation's first grant, roughly $110,000, went to Emory's Egleston Children's Research. Marcus also provided initial funding to launch Autism Speaks in 2005 and built the Marcus Stroke and Neuroscience Center at Grady, the Marcus Autism Center at Children's Healthcare of Atlanta, and the Marcus Institute for Brain Health at the University of Colorado Anschutz Medical Campus, which treats veterans and retired athletes with traumatic brain injuries.

His giving was deliberate. "We decided to narrow the field to those things that I was really, truly interested in," Marcus told Philanthropy Roundtable in 2012, describing his shift away from what he called a "buckshot approach." Trustee Mike Leven added, "People may not understand how hard it is to do this. People are coming at you all the time, good people with good causes. Unless you discipline yourself, you're going to overgive and underachieve. Bernie's better at it than anybody I know."
