H. Anthony Belzberg was a pioneering and prominent Canadian businessman and investor, best known as one of the three Belzberg brothers—along with Samuel and Isidore—who built a substantial family fortune starting from modest beginnings in the garment and dry cleaning business in post-World War II Canada. Born into a Jewish immigrant family from Eastern Europe, the Belzbergs transitioned into finance and investments in the 1950s, founding Belzberg & Company (later Belzberg Investments) in Calgary, Alberta. Under their leadership, the firm expanded aggressively into real estate, oil and gas exploration, resource ventures, and corporate arbitrage, particularly during the 1970s and 1980s when they gained notoriety for acquiring significant stakes in undervalued companies and engaging in takeover battles. Their investment strategies, often involving greenmail tactics where they bought shares to force companies to repurchase them at a premium, drew criticism from regulators and corporate executives, leading to investigations by the U.S. Securities and Exchange Commission (SEC) in the 1980s for alleged insider trading and market manipulation, though no major convictions resulted. H. Anthony Belzberg played a key role in these ventures, contributing to the family's peak net worth estimated in the billions during their heyday. The Belzberg Group's influence extended beyond business into philanthropy, with the family establishing foundations supporting Jewish education, healthcare, and community initiatives in Canada and Israel. H. Anthony Belzberg was the father of Marc Belzberg, who later pursued his own path in business and investments, influenced by his father's entrepreneurial legacy. The brothers' firm faced challenges in the late 1980s amid market downturns and regulatory scrutiny, leading to a restructuring where they sold off assets and shifted focus to private investments. Despite controversies, including lawsuits from companies like Southam Inc. over hostile bids, the Belzbergs are credited with pioneering aggressive investment strategies in Canada. H. Anthony Belzberg retired from active management in the 1990s, maintaining a low public profile thereafter, while the family continued their legacy through diversified holdings in resources and finance.
