In a red tee under a blazer, roomy trousers and a hat, an 88-year-old man saunters through the door of an old building. Just as he reaches his car stationed in the lot, he turns to look into the camera and smiles. This is Alan Berg. "I think it is a great idea to make a film on him [Berg]; he is deeply embarrassed by it," says a family friend as the camera moves into a small office, where the documentary, A Full Bowl: The Alan Berg Story, was shot.

The 50-minute film that recently dropped on YouTube is made by American filmmaker, photographer and writer Theo Schear. It is an ode to a man who made remarkable efforts to combat hunger and malnutrition during the JFK and Johnson years in the White House where he led Food for Peace, a food aid programme that used US food surpluses in ways that would benefit both, the United States and help food-needy countries, and later the World Bank as Senior Nutrition Officer (1972-95). Most notable was his widespread implementation of strategies to address malnutrition, especially among children and pregnant women through a career that spanned half a century. It was no wonder that he was called "the conscience of the Bank on hunger issues".
