Mario Joseph Gabelli is an American businessman, the self-made billionaire Founder, Chairman, and CEO of GAMCO Investors, Inc. (NYSE: GBL), a major asset management and financial services firm. His career is rooted in elite finance and fundamental value investing.

Gabelli graduated from Fordham University (1965) with a B.A. and earned an MBA from Columbia Business School (1967). His philosophical approach centers on fundamental, bottom-up research and identifying private market value (PMV) in publicly traded companies, often leading to activist investment (a strategy honed by his early work at Loeb, Rhoades & Co.). His structural wealth is tied to his controlling stake in his publicly traded firm and its specialized funds.
