Charlie Munger (January 1, 1924 - November 28, 2023) was an American investor, businessman, attorney, and philanthropist, best known as the longtime vice chairman of Berkshire Hathaway. Widely regarded as one of the greatest business thinkers of his generation, Munger played a key role in shaping Berkshire Hathaway alongside Warren Buffett.
His multidisciplinary approach to decision-making and focus on rational thinking changed the way many investors and entrepreneurs approach business and life.
Originally trained as a lawyer, Munger developed an investment philosophy that went beyond traditional financial analysis. He promoted the use of "mental models"—drawing insights from psychology, economics, mathematics, biology, history, and other fields—to make better decisions. His influence encouraged investors to focus on acquiring exceptional businesses with strong, lasting competitive advantages rather than just seeking statistically cheap investments.
Known for his sharp wit, honesty, and straightforward communication, Munger often spoke about the importance of patience, lifelong learning, integrity, and avoiding common cognitive biases. His speeches and writings have become fundamental resources for investors, business leaders, and decision-makers aiming to improve their judgment
and critical thinking
Munger's legacy extends well beyond investing. His philosophy of continuous learning, rationality, and disciplined decision-making has inspired generations of entrepreneurs, executives, and investors worldwide. His lifelong partnership with Warren Buffett remains one of the most successful collaborations in business history, exemplifying the lasting value of clear thinking, sound judgment, and unwavering principles.
