Howard William Lutnick is an American billionaire businessman, who succeeded Bernard Gerald Cantor as the head of Cantor Fitzgerald. Lutnick is the chairman and CEO of Cantor Fitzgerald and BGC Group. After losing 658 employees, including his brother, in the September 11 attacks, Lutnick survived the subsequent collapse of the towers on the ground, and has since become known for his charity efforts through the Cantor Fitzgerald Relief Fund, which helps to aid families of victims of the attacks and natural disasters.
