The month-long election for NPR’s Board of Directors closed Monday, with two incumbents and two new faces joining the board. NPR announced Tuesday that Mike Crane, director of Wisconsin Public Radio in Madison, and Mike Savage, g.m. of WBAA in West Lafayette, Ind., will join the board. For what is believed to be the first time, Savage got on the ballot with a written petition signed by at least 15 authorized representatives. Candidates are usually picked by a selection committee headed by the NPR board chair. Incumbents Caryn Mathes, g.m. of KUOW in Seattle, and Flo Rogers, c.e.o. of KNPR in Las Vegas, were re-elected to second terms, and Patricia Diaz Dennis and former NPR interim CEO Paul G. Haaga Jr. were re-elected as public directors.
