Knell, president and CEO of the public radio network, will take on the same role at the National Geographic Society this fall. Knell, who assumed his current role in 2011, will stay with NPR until the fall to work with the Board to ensure a smooth transition as it launches a search for his successor.
Gary Knell, the longtime president and CEO of Sesame Workshop, becomes head of NPR on Dec. 1, succeeding Vivian Schiller, who resigned under pressure in March after a former NPR fundraiser was caught on camera calling the tea party racist.
