NPR President Gary Knell has taken a new job as the chief executive of the National Geographic Society.
Knell will succeed the society's current president, John Fahey, when his term at NPR ends in late fall.
Knell has served as CEO of NPR since December 2011. He came to the position after heading Sesame Workshop.
"I am deeply honored to have been chosen to lead this incredible organization as it celebrates 125 years of educating people through its media about the world in which we live," Knell said in the release.
"It has taken a great deal of personal reflection on my part to reach this decision," Knell said in a letter to NPR employees. "NPR is and will always be a beacon of journalistic integrity, commitment, and courage . . . Thank you for giving me the opportunity to work with you."
