Shafik Gabr built ARTOC, a conglomerate with interests in steel fabrication, prefabricated factories, and logistical services for oil and gas companies. Instability in Egypt has hurt business, with revenues declining 20% in 2012. That explains the nearly $300 million drop in Gabr's net worth since last year. The uprising in Egypt created an impetus for Gabr to establish a foundation in the U.S. last year. He spends 40% of his time promoting East-West dialogue through arts, science, and entrepreneurship.This past April, his eponymous foundation selected 20 Egyptians and Americans who engaged in cross cultural activities, culminating in October with a visit to five U.S. cities.
