Michel du Cille, the 58-year-old Pulitzer Prize-winning Washington Post photojournalist, died on Thursday while on assignment in Liberia. He collapsed while returning on foot from a village where he was working on a project; he was taken to a hospital but was declared dead upon arrival of an apparent heart attack. Du Cille, who documented international and domestic crises for the past four decades, wrote about his experience covering Ebola in October. He will be remembered by his stunning portfolio of poignant, powerful photographs that exposed his subjects' hardships and suffering; his courage and talent will continue to serve as an inspiration to others.
