Grace T.S. was the author's first wife.Richard Watson Gilder (1844 1909) was editor of The Century Magazine from 1881 until his death. Under Gilder's editorship, The Century became one of the most esteemed periodicals in the country and Gilder himself became influential enough that his biographer Herbert Smith referred to the 1880s as "the Gilder Age." He published the works of William Dean Howells, Henry James, Mark Twain, and Walt Whitman. Clarence Clough Buel (1850 1933) joined the staff of Century Magazine in 1881. In 1883, in conjunction with Robert Underwood Johnson, he began the editing of the Century articles on the American Civil War. These articles were afterward expanded and compiled into the book Battles and Leaders of the Civil War (1887). He was associate editor of Century Magazine 1909-13, advisory editor until May 1914.Robert Underwood Johnson (1853 1937) was a proponent of the establishment of international copyright protections and one of the driving forces behind the creation of Yosemite National Park. Some letters are headed with Seton's residence, Wyndygoul in Cos Cob, Connecticut. It was at Wyndygoul that Seton recruited local schoolboys to explore the woodlands and study nature, establishing the Seton Woodcraft Indians, a precursor to the Boy Scouts of America. Eventually Seton sold his estate to Maurice Wertheim in 1913 for the then-astonishing sum of $250,000. Wertheim was the Secretary of the United Cigar Manufacturers Association and later the eponymous founder of Wertheim & Company, a New York City investment firm. He and his wife Alma Morgenthau retained Wyndygoul as a summer home and it eventually evolved into a family compound. It was at Wyndygoul that their daughter Barbara Tuchman wrote the The Guns of August, winning the 1962 Pulitzer Prize for her book about the run-up to the First World War.
