Context paragraphs:
My Gal Sal: My Gal Sal is a 1942 20th Century Fox musical starring Rita Hayworth and Victor Mature.  The film is a biopic of 1890s composer and songwriter Paul Dresser and singer Sally Elliot.  It was based on a biographical essay, sometimes erroneously referred to as a book, by Dresser's younger brother, novelist Theodore Dreiser.  (Dreiser was the original family name.)  Some of the songs portrayed as Dresser's work were actually written by him, but several were created for the film by the Hollywood songwriting team of Ralph Grainger and Leo Robin.

The Stoic: The Stoic is a novel by Theodore Dreiser, first published in 1947.  It is the conclusion of his "Trilogy of Desire", a series of novels about Frank Cowperwood, a businessman based on the real-life streetcar tycoon Charles Yerkes.  Dreiser completed "The Stoic" only days before his death in 1945 and the book was published posthumously.

Horses and Men: Horses and Men (full title: "Horses and Men: Tales, long and short, from our American life") is a 1923 short story collection by the American author Sherwood Anderson.  It was Anderson's fourth book to be published by B.W. Huebsch and his third collection after the successful short story cycle "Winesburg, Ohio".  The book was dedicated to writer Theodore Dreiser and included a two-page essay about him titled "Dreiser" in addition to a Forward and nine stories.

Theodore Dreiser: Theodore Herman Albert Dreiser ( ; August 27, 1871 – December 28, 1945) was an American novelist and journalist of the naturalist school.  His novels often featured main characters who succeeded at their objectives despite a lack of a firm moral code, and literary situations that more closely resemble studies of nature than tales of choice and agency.  Dreiser's best known novels include "Sister Carrie" (1900) and "An American Tragedy" (1925).  In 1930 he was nominated to the Nobel Prize in Literature.

The Titan (novel): The Titan is a novel written by Theodore Dreiser in 1914.  It is the second book in Dreiser's "Trilogy of Desire", in which it is the sequel to "The Financier".

The &quot;Genius&quot; (novel): The "Genius" is a semi-autobiographical novel by Theodore Dreiser, first published in 1915.  It concerns Eugene Witla, a talented painter of strong sexual desires who grapples with his commitment to his art and the force of his erotic needs.  The book sold 8,000 copies in the months immediately following publication but encountered legal difficulties when it was declared potentially obscene.  Dreiser's publisher was nervous about continuing publication and recalled the book from bookstores, and the novel did not receive broad distribution until 1923.  When "The "Genius"" was reissued by a different publisher, the firm of Horace Liveright, it immediately sold more than 40,000 copies.

Murder of Grace Brown: Grace Mae Brown (March 20, 1886 – July 11, 1906) was an American skirt factory worker whose murder caused a nationwide sensation, and whose life inspired the fictional character Roberta Alden in the 1925 Theodore Dreiser novel, "An American Tragedy", as well as the 2003 Jennifer Donnelly novel, "A Northern Light".  The facts of the real murder are laid out in the two non-fiction books, both published in 1986: "Adirondack Tragedy: The Gillette Murder Case of 1906", written by Joseph W. Brownell and Patricia A. Wawrzaszek, and "Murder in the Adirondacks: An American Tragedy Revisited", by Craig Brandon.  Shelley Winters was nominated for the Academy Award for Best Actress for her performance in the role inspired by Grace Brown (with the name changed to 'Alice Tripp') in the 1951 film "A Place in the Sun," loosely based on the Dreiser novel.

Old Rogaum and His Theresa: "Old Rogaum and His Theresa" is a short story written by Theodore Dreiser.  It was originally published in "Reedy's Mirror" on December 12, 1901 under the title of "Butcher Rogaum's Door."  It subsequently appeared in the 1918 volume "Free and Other Stories".  With this short story, Dreiser begins to move from allegory to realism dealing with issues including sexual behavior, city life, immigrant struggles, and the conflicts between children and their parents.

Fortean Society: The Fortean Society was started in the United States in 1931 during a meeting held in the New York flat of Charles Hoy Fort in order to promote the ideas of American writer Charles Fort.  The Fortean Society was primarily based in New York City.  Its first president was Theodore Dreiser, an old friend of Charles Fort, who had helped to get his work published.  Founding members of The Fortean Society included Tiffany Thayer, Booth Tarkington, Ben Hecht, Alexander Woollcott (and many of NYC's literati such as Dorothy Parker), and Baltimore writer H. L. Mencken.  Other members included Vincent Gaddis, Ivan T. Sanderson, A. Merritt, Frank Lloyd Wright and Buckminster Fuller.  The first 6 issues of the Fortean Society's newsletter "Doubt" were each edited by a different member, starting with Theodore Dreiser.  Tiffany Thayer thereafter took over editorship of subsequent issues.  Thayer began to assert extreme control over the society, largely filling the newsletter with articles written by himself, and excommunicating the entire San Francisco chapter, reportedly their most active, after disagreements over the society's direction, and forbidding them to use the name Fortean.  During World War II, for example, Thayer used every issue of "Doubt" to espouse his politics.  Particularly, he frequently expressed opposition to Civil Defense, going to such lengths as encouraging readers to turn on their lights in defiance to air raid sirens.  In contrast to the spirit of Charles Fort, he not only dismissed flying saucers as nonsense, but also dismissed the atomic bomb as a hoax.
