For fourteen years he gave of his initiative and strength, as well as his money. His ideas took material form, and the park system came into being as he had planned. His work was recognized and appreciated. In 1921 George Washington University bestowed upon him the honorary degree of Doctor of Law. His alma mater, the University of California, conferred the same degree in 1924. President W. W. Campbell on that occasion characterized him as follows: “Stephen Tyng Mather, mountaineer and statesman; lover of Nature and his fellow-men; with generous and farseeing wisdom he has made accessible for a multitude of Americans their great heritage of snow-capped mountains, of glaciers and streams and falls, of stately forests and quiet meadows.” In 1926 he was awarded the gold medal of the National Institute of Social Sciences for his service to the nation in national parks development. The American Scenic and Historical Preservation Society awarded the Pugsley gold medal in recognition of his national and state park work, and he was made an honorary member of the American Society of Landscape Architects.[23] In the fall of 1928, Mather’s health failed. He suffered a stroke of paralysis which forced his retirement from public service in January, 1929. For more than a year he fought to regain his strength but in January, 1930, he was suddenly stricken and died quickly. Indeed, “the world is much the poorer for his passing, as it is much the richer for his having lived.” One of Mather’s first acts as Director of the National Park Service was to appoint a strong man to the superintendency of Yosemite National Park. On the staff of the Geological Survey was an engineer of distinction, Washington B. (“Dusty”) Lewis. Mather appointed him to the Yosemite task and he became the first park superintendent on March 3, 1916. The Yosemite problems were complicated and trying from the beginning. The park was, even then, attracting more visitors than had been provided for. Public demands kept steadily ahead of facilities that could be made available through government appropriations. For more than twelve years W. B. Lewis expended his energy and ingenuity in bringing the great park through its formative stages.
