Question: Were both Henry James and Charlotte Perkins Gilman both american writers?
Context: Herland is a utopian novel from 1915, written by feminist Charlotte Perkins Gilman.  The book describes an isolated society composed entirely of women, who reproduce via parthenogenesis (asexual reproduction).  The result is an ideal social order: free of war, conflict, and domination.  It first appeared as a serial in "The Forerunner", a magazine edited and written by Gilman between 1909 and 1916.  The book is the middle volume in her utopian trilogy; it was preceded by "Moving the Mountain" (1911), and followed with a sequel, "With Her in Ourland" (1916).  It was not published in book form until 1979. Women and Economics – A Study of the Economic Relation Between Men and Women as a Factor in Social Evolution is a book written by Charlotte Perkins Gilman and published in 1898.  It is considered by many to be her single greatest work, and as with much of Gilman’s writing, the book touched a few dominant themes: the transformation of marriage, the family, and the home, with her central argument: “the economic independence and specialization of women as essential to the improvement of marriage, motherhood, domestic industry, and racial improvement.” Charlotte Perkins Gilman ( ); also Charlotte Perkins Stetson (July 3, 1860 – August 17, 1935), was a prominent American feminist, sociologist, novelist, writer of short stories, poetry, and nonfiction, and a lecturer for social reform.  She was a utopian feminist and served as a role model for future generations of feminists because of her unorthodox concepts and lifestyle.  Her best remembered work today is her semi-autobiographical short story "The Yellow Wallpaper" which she wrote after a severe bout of postpartum psychosis. Moving the Mountain is a feminist utopian novel written by Charlotte Perkins Gilman.  It was published serially in Perkins Gilman's periodical "The Forerunner" and then in book form, both in 1911.  The book was one element in the major wave of utopian and dystopian literature that marked the later nineteenth and early twentieth centuries.  The novel was also the first volume in Gilman's utopian trilogy; it was followed by the famous "Herland" (1915) and its sequel, "With Her in Ourland" (1916). Adeline E. Knapp (March 14, 1860 – c. June 1909) was an American journalist, author, social activist, environmentalist and educator, who is today remembered largely for her tempestuous lesbian relationship with Charlotte Perkins Gilman.  In her lifetime, Knapp was known as a fixture of the turn-of-the-century San Francisco Bay Area literary scene.  An outspoken writer who often addressed controversial topics in her columns for the "San Francisco Call", Knapp wrote on a wide range of subjects from livestock to the Annexation of Hawaii.  Though often drawn to progressive causes like child labor and conservation, Knapp also tended to espouse reactionary views, as evidenced by her anti-Chinese sentiments and criticisms of the women's suffrage movement.  At a time when many American women were joining the movement to extend political and voting rights to women, Knapp spoke in state senate hearings in New York expressing doubts about the benefits of suffrage to women, and she allowed her speeches and letters on the topic to be used as propaganda by the anti-suffragism movement.  Knapp was also the author of numerous short stories, as well as a novel set in the Arizona desert—works reflecting her outdoor enthusiast sensibilities, keen intellect, and interest in Western regionalism.  These works, though praised in her lifetime, today have few readers among enthusiasts of Western fiction.

"Campus Life" (1987) looked at the history of undergraduate cultures from the 18th century to the present, with attention to college men (and later, women), outsiders, and rebels.  "The Power and Passion of M. Carey Thomas", president of Bryn Mawr College and feminist, 1857-1935, appeared in 1984.  "Rereading Sex" (2002), explored sexual representations and the campaign to censor them that led to the landmark Comstock Law of 1873 that barred obscene materials, contraceptive information and devices, and abortion advertisements from the US mails.  "The Flash Press" (2008), co-authored with Patricia Cline Cohen and Timothy Gilfoyle, inquired into the sporting weeklies of New York City in the 1840s.

Henry James, OM ((1843--)15 1843 – (1916--)28 1916 ) was an American author regarded as a key transitional figure between literary realism and literary modernism, and is considered by many to be among the greatest novelists in the English language.  He was the son of Henry James, Sr. and the brother of renowned philosopher and psychologist William James and diarist Alice James.

With Her in Ourland: Sequel to Herland is a feminist novel written by Charlotte Perkins Gilman, and originally published in 1916 in Gilman's self-authored and edited periodical "The Forerunner".  As its subtitle indicates, the book is the sequel to Perkins Gilman's "Herland", published in the previous year, 1915. The Forerunner was a monthly magazine produced by Charlotte Perkins Gilman (best known as the writer of "The Yellow Wallpaper"), from 1909 through 1916.  During that time, she wrote all of every issue — editorials, critical articles, book reviews, essays, poems, stories, and six serialized novels.  Gilman’s drive for social change was the inspiration for "Forerunner" and its controversial articles.  She succeeded in administering progressive ideas for change to the magazine's readers, growing support for her desires during the women's suffrage movement.  The magazine was based in New York City.
