Charlie Munger, the late Berkshire Hathaway vice‑chairman who Warren Buffett dubbed “the architect” of the company’s success, helped build one of history’s greatest investment engines. In his 80s—when most people are winding down—Munger quietly partnered with a 17‑year‑old neighbor who was struggling academically, had no college plans, and mistakenly thought Munger was Jewish. A recent Wall Street Journal piece on Munger’s final years revealed this surprising chapter.

    In 2005, a teenager named Avi Mayer knocked on Munger’s Los Angeles door, holding a Hebrew Bible and hoping to connect with a man he believed shared his faith. Munger wasn’t Jewish, but he opened the door. Mayer, who had ADHD and felt lost while his peers prepared for college, was offered a different path. At 81, Munger saw potential and suggested Mayer skip college entirely and attend what he jokingly called “Munger University.” They spent time together; Munger provided books, lessons, and even arranged kosher meals so they could dine together. He offered structure, insight, and respect—something Mayer had been missing.

    Years later, when Mayer teamed up with his childhood friend Reuven Gradon to explore real estate, Munger kept a close eye. He watched their early moves, offered feedback, and then gave them what few billionaires would: his backing. “I’m graduating you,” Munger reportedly told them, a graduation that came with capital and mentorship.

    From around 2017, the trio began acquiring garden‑style apartment complexes in Southern California. They prioritized livability over luxury, insisting on trees, low‑density design, and thoughtful landscaping. Munger even helped choose paint colors and reviewed floor plans. These were long‑term investments financed with fixed‑rate debt, contrary to other investors chasing short‑term gains. Munger’s guidance ensured the properties were built for lasting value rather than fleeting trends.
