Walter Lippmann (September 23, 1889 – December 14, 1974) was an American writer, reporter, and political commentator famous for being among the first to introduce the concept of Cold War, coining the term "stereotype" in the modern psychological meaning, and critiquing media and democracy in his newspaper column and several books, most notably his 1922 book "Public Opinion".
 Lippmann was also a notable author for the Council on Foreign Relations, until he had an affair with the editor Hamilton Fish Armstrong's wife, which led to a falling out between the two men.
 Lippmann also played a notable role in Woodrow Wilson's post World War I board of inquiry, as its research director.
 His views regarding the role of journalism in a democracy were contrasted with the contemporaneous writings of John Dewey in what has been retrospectively named the Lippmann-Dewey debate.
 Lippmann won two Pulitzer Prizes, one for his syndicated newspaper column "Today and Tomorrow" and one for his 1961 interview of Nikita Khrushchev.
Drift and Mastery: An Attempt to Diagnose the Current Unrest is the second book by American journalist and political thinker Walter Lippmann.
 Published in the Fall of 1914, "Drift and Mastery" argues that rational scientific governing can overcome forces of societal drift.
 Lippmann argued that due to the profound social and economic change old ideas and institutions lacked relevance.
 Specifically, "Drift and Mastery" warns against a reliance on broad theories and the framework of competition and self-interest.
 Democracy and society at large, he argued, was unable to address problems because it was adrift, lacking intentionality and discipline.
 Lippmann's prescription in "Drift and Mastery" was deliberate and scientific governing, what he termed mastery.
 This forward-looking progressive vision sought a better society through rational, scientific order, while rejecting Marxist, Utopian and traditionalist thinking.
 "Drift and Mastery" received enormously positive reviews, establishing Lippmann as an important public intellectual and figure within the progressive movement.
 Although Lippmann later lost faith in the promise of science and rationality in government, "Drift and Mastery" was and is regarded as an important document of the progressive movement.
William Bolitho Ryall (1891–1930) was a South African journalist, writer and biographer who was a valued friend of prominent writers such as Ernest Hemingway, Noël Coward, Walter Lippmann and Walter Duranty.
 He wrote under the name ‘William Bolitho’ but was known to his friends as ‘Bill Ryall’.
 He died on 2 June 1930 at the age of 39 just as his reputation was being established.
H. P. Lovecraft is the debut album by the American psychedelic rock band H. P. Lovecraft and was released in October 1967 by Philips Records.
 It blended psychedelic and folk rock influences and was marked by the haunting, eerie ambiance of the band's music, which itself was often inspired by the literary works of horror writer H. P. Lovecraft, after whom the band had named themselves.
 Although most of the album comprises interpretations of traditional and contemporary folk songs, it also features the self-penned compositions "That's How Much I Love You, Baby (More or Less)", "The Time Machine", and arguably the band's best known song, "The White Ship".
 The traditional song "Wayfaring Stranger" was released as a single just ahead of the album in September 1967 and "The White Ship" was issued shortly after the album appeared, although neither single reached the charts.
 Like its attendant singles, "H. P. Lovecraft" was also somewhat commercially unsuccessful and failed to reach the "Billboard" Top LPs chart or the UK Albums Chart, although it did sell reasonably well over time.
Howard Phillips Lovecraft ( ; August 20, 1890 – March 15, 1937) was an American author who achieved posthumous fame through his influential works of horror fiction.
 He was virtually unknown and published only in pulp magazines before he died in poverty, but he is now regarded as one of the most significant 20th-century authors in his genre.
 Lovecraft was born in Providence, Rhode Island, where he spent most of his life.
 Among his most celebrated tales are "The Call of Cthulhu" and "The Shadow over Innsmouth", both canonical to the Cthulhu Mythos.
 Lovecraft was never able to support himself from earnings as author and editor.
 He saw commercial success increasingly elude him in this latter period, partly because he lacked the confidence and drive to promote himself.
 He subsisted in progressively strained circumstances in his last years; an inheritance was completely spent by the time that he died at age 46.
Katherine 'Kay' Murphy Halle (1904–1997) was a Cleveland journalist, author, radio broadcaster, department store heiress, World War II intelligence operative with the Office of Strategic Services, and intimate confidant and/or mistress of many luminaries of the 20th century, including George Gershwin, Randolph Churchill, W. Averell Harriman, Joseph P. Kennedy, Walter Lippmann, and Buckminster Fuller.
 She compiled and edited "Irrepressible Churchill: A Treasury of Winston Churchill's Wit" in 1966.
The Walter Lippmann Colloquium, in French Colloque Walter Lippmann, was a conference of intellectuals organized in Paris in August 1938 by French philosopher Louis Rougier.
 After interest in classical liberalism had declined in the 1920s and 1930s, the aim was to construct a new Liberalism as a rejection of collectivism, socialism and laissez-faire liberalism.
 At the meeting the term neoliberalism was coined by Alexander Rüstow referring to the rejection of the (old) laissez-faire liberalism.
The Phantom Public is a book published in 1925 by journalist Walter Lippmann in which he expresses his lack of faith in the democratic system by arguing that the public exists merely as an illusion, myth, and inevitably a phantom.
 As Carl Bybee wrote, "For Lippmann the public was a theoretical fiction and government was primarily an administrative problem to be solved as efficiently as possible, so that people could get on with their own individualistic pursuits" (48).
"The White Ship" is a song released by the American psychedelic rock band, H. P. Lovecraft, in November 1967.
 The songwriting is credited to band members George Edwards, Dave Michaels, and Tony Cavallari.
 Acting as the opening song on the second side of their debut LP, "H. P. Lovecraft", it was the album's longest track, and an edited version was also released as the band's second single.
 The name and theme of the song derive directly from author H. P. Lovecraft's short story, "The White Ship".
 Despite its failure to chart nationally, it is widely considered to be H. P. Lovecraft's most accomplished piece, and helped establish the group, who were originally from Chicago, in the West Coast music scene.
The Cthulhu Mythos is a shared fictional universe, based on the work of American horror writer H. P. Lovecraft.
 The term was coined by August Derleth, a contemporary correspondent and protégé of Lovecraft's, to identify the settings, tropes, and lore employed by Lovecraft and his literary successors.
 The name "Cthulhu" derives from the central creature in Lovecraft's seminal short story, "The Call of Cthulhu", first published in the pulp magazine "Weird Tales" in 1926.
 Richard L. Tierney, a writer who also wrote "Mythos" tales, later applied the term "Derleth Mythos" to distinguish Lovecraft's works from Derleth's later stories, which modify key tenets of the "Mythos".
 Authors of Lovecraftian horror in particular frequently use elements of the Cthulhu Mythos.
