Robert Sterling Yard [SEP] Introduction
Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916. Yard served as head of the National Parks Educational Committee for several years after its conception, but tension within the NPS led him to concentrate on non-government initiatives.
