After the war, he moved to Washington, DC where he took charge of a foundering trucking company. With no formal training – only his innate business savvy, powerful personality, and growing leadership ability – he turned the company around and led it to success. Great American Van Lines and Forwarders, with Jack Kagan at the helm, helped lead the transportation industry into the future. He also owned and managed a diverse number of transportation assets, from steamship lines to warehouses, and from import/export to long-haul trucks.
Jack fell ill and passed on February 2014. He established the Jack Kagan Foundation, with four major missions in mind: as an orphan, he wanted to provide assistance to other orphaned, fostered, or otherwise challenged children; as a veteran, he wanted to help the veterans of our nation – especially those mentally or physically disabled; as a supporter of science, he wanted to fund medical services and promising medical science research; and as a man who valued his community, he wanted to ensure his Foundation provided for worthy community efforts. His surviving children, the Trustees of his Foundation, are ensuring his charitable grants meet the mission of the Foundation in his name.
