Book excerpt: PICTURES ON THE RADIO compiles the work of David Gilkey, a celebrated conflict photographer who helped NPR bring vivid life to big and small stories with global impact. Known for chronicling pain and beauty in war and conflict, he was on assignment in Helmand, Afghanistan in 2016 when he and NPR's Afghan interpreter, Zabihullah Tamanna were killed by a Taliban ambush of their convoy. Considered one of the best photojournalists in the world, his death made headlines around the country and the globe. The nine chapters in PICTURES ON THE RADIO include photographs from assignments in Afghanistan, Haiti, and Gaza covering war, natural disasters, and political strife, but also a surreal journey on the tran-Siberian railroad, a voyage down the Ganges, and coverage of American war-veterans showcasing Gilkey's range as a photojournalist whose work captured the strength and fragility of our humanity and our planet. An essay by NPR correspondents--including Jason Beaubien, Ari Shapiro, David Greene, Julie McCarthy, and Eric Westervelt--who accompanied David on assignment introduces each chapter of award-winning photographs and an afterword by Alyda Gilkey paints a portrait of the man behind the camera. PICTURES ON THE RADIO continues David Gilkey's lifelong mission of connecting Americans to the frontlines far beyond their shores. The drama, beauty and dignity of his subjects continue to move the heart and the conscience.
