David Seidler, a screenwriter whose Oscar-winning script for “The King’s Speech” — about King George VI conquering a stutter to rally Britain at the outset of WWII — drew on his own painful experience with a childhood stammer, died on March 16 on a fly-fishing trip in New Zealand. He was 86 and lived in Santa Fe, NM.

On winning the Academy Award for best original screenplay for “The King’s Speech” (2010), Mr. Seidler said from the Hollywood stage that he was accepting on behalf of all stutterers. “We have a voice; we have been heard,” he said.
