I am also a Mather, descendant of Richard Mather, first of line of Mather's from England and therefore a distant relative of Stephen T. Mather. As I travel the country, in truck and trailer, I am visiting sites of his memorial plaques. My research found that It was designed by a world class sculpturer, Bryant Baker. In 1932 his family and friends established the Stephen Mather Memorial Fund, which commissioned numerous bronze plaques honoring Mather's accomplishments and installed them in national park units.When he retired in 1929, Mather had a position of being Director for 12 years, and 52 NP and NM total. On July 4, 1932, 16 parks had ceremonies and dedications of these new plaques, including Yosemite. A second generation of plaques was made in 1958 (14); and a third generation was made in 1986-91. I have attached list of all Memorial Plaques that I can find in the US. Please feel free to add additional ones and locations to these submitted. Thank you. Jeff L. Mather
