In a memo to staff, AP President Gary Pruitt remembered Niedringhaus as "spirited, intrepid and fearless, with a raucous laugh that we will always remember."
"Anja is the 32nd AP staffer to give their life in pursuit of the news since AP was founded in 1846," he wrote. "This is a profession of the brave and the passionate, those committed to the mission of bringing to the world information that is fair, accurate and important. Anja Niedringhaus met that definition in every way."
