Marcus grew up in Newark, New Jersey to Russian immigrant parents, and went on to start Home Depot. His retail success helped him accumulate $1.5 billion in net worth. His philanthropic efforts include funding the Georgia Aquarium and starting the Marcus Foundation. Not wanting his kids to inherit large sums of money — for their own good, he says — Marcus plans on giving the majority of his Home Depot stock to his foundation, which benefits the handicapped and education.
