Stephen Tyng Mather (July 4, 1867 – January 22, 1930) was an American industrialist and conservationist who was the first director of the National Park Service. As president and owner of Thorkildsen-Mather Borax Company he became a millionaire. With his friend the journalist Robert Sterling Yard, Mather led a publicity campaign to promote the creation of a unified federal agency to oversee National Parks administration, which was established in 1916. In 1917, Mather was appointed to lead the NPS, the new agency created within the Department of the Interior. He served until 1929, during which time Mather created a professional civil service organization, increased the numbers of parks and national monuments, and established systematic criteria for adding new properties to the federal system. Early life Stephen Tyng Mather was born July 4, 1867, in San Francisco, and named for the prominent Episcopal minister Stephen Tyng of New York, who was admired by his parents, Joseph W. Mather and Bertha Jemima Walker. Mather was educated at Boys' High School (now Lowell High School) in San Francisco, and graduated from the University of California at Berkeley in 1887. His family moved to New York, where Mather worked as a reporter for the New York Sun until 1893. During that time he met and befriended Robert Sterling Yard, another reporter, who would become a close friend. In 1893 Mather married Jane Thacker Floy of Elizabeth, New Jersey, with Yard serving as his best man. They had one daughter, Bertha Floy Mather. In 1906, Mather became the sole owner of the Mather family homestead in Connecticut, which had been built by his great-grandfather about 1778. He and his family used it during the summers and he regarded it as his true home. Business career Mather started working for the Pacific Coast Borax Company at its headquarters in New York, where his father was administrator. Borax is a component of a variety of detergents and compounds, which was mined almost exclusively in California. Borax is a commodity, and as such, one brand is essentially as good as another. For a company to be successful, it had to mine the product more cheaply, process it more efficiently, or market it more aggressively. In 1894 the younger Mather moved with his wife to Chicago, where he established a distribution center for the company. In this role, he proved vital in advertising and sales promotion for the company.
