Mario Gabelli was born in The Bronx, New York, to Italian immigrant parents. His early fascination with markets was unusual—he would read stock tables as a boy and bought his first stock at age 13.
He graduated summa cum laude from Fordham University in 1965, studying accounting and economics. Later, he earned an MBA from Columbia Business School, where he was influenced by professors connected to Benjamin Graham’s value-investing legacy.
