Problem: "Hound Dog" is a twelve-bar blues song written by Jerry Leiber and Mike Stoller. Recorded originally by Willie Mae "Big Mama" Thornton on August 13, 1952, in Los Angeles and released by Peacock Records in late February 1953, "Hound Dog" was Thornton's only hit record, selling over 500,000 copies, spending 14 weeks in the R&B charts, including seven weeks at number one. Thornton's recording of "Hound Dog" is listed as one of the Rock and Roll Hall of Fame's "500 Songs That Shaped Rock and Roll", and was inducted into the Grammy Hall of Fame in February 2013. "Hound Dog" has been recorded more than 250 times. The best-known version is the July 1956 recording by Elvis Presley, which is ranked number 19 on Rolling Stone magazine's list of the 500 Greatest Songs of All Time; it is also one of the best-selling singles of all time.

Two records were released that were neither cover versions of nor answers to Thornton's release, yet used a similar melody without any attribution to Leiber and Stoller. The first was Smiley Lewis's "Play Girl", credited to D. Bartholomew and released by the Imperial Records label (Imperial 45-5234) by the end of March 1953. Described as a "stomping uptempo boogie rocker", it began: "You ain't nothin' but a Play Girl / Staying out all night long". In April 1955, female impersonator Jesse "Big 'Tiny'" Kennedy recorded "Country Boy" accompanied by His Orchestra that was released by RCA's Groove Records (Groove 4G-0106) by May 21. While credited solely to Kennedy, this song has a similar melody to "Hound Dog": "'Country Boy' has a deceptively slouching flip on the 'Hound Dog' motif - this time with Tiny proclaiming proudly that he 'ain't nothing but a country boy'". In the early 1970s Robert Loers, owner of Dutch label Redita Records, found a song with the same melody as "Hound Dog" called "(You Ain't Nuttin' But a) Juicehead" on an anonymous acetate at Select-o-Hits, the Memphis distributorship owned by Sam Phillips' brother, Tom, where Sun artifacts were stored. When Juice Head first appeared on a Redita Records LP [in 1974], it was credited to Rosco Gordon. But it's not Rosco. It simply is not him. Really. Even Rosco confirmed that. It might not even be a Memphis Recording Service demo. Just substitute the words "Hound Dog" for "Juice Head" and what have you got? Of course the inspiration for this song came from Big Mama Thornton's "Hound Dog" or perhaps even from Rufus Thomas' "Bear Cat". But the song's other parent is Eddie Vinson's slowed down "Juicehead Blues" which harks to the previous decade...If indeed this originated from Sam Phillips' studio, it was nothing that Phillips needed to touch because it was another lawsuit waiting to happen." Philip H. Ennis sees "Two Hound Dogs", which was recorded on May 10, 1955, by Bill Haley & His Comets (Decca 29552), as a response to Thornton's recording. While not an answer record in the traditional sense, the lyric characterized "Rhythm" and "Blues" as the titular "Two Hound Dogs," an apparent testament to the stature of "Hound Dog."

What year was this

Answer with quotes: 1955,

Problem: Walter "Walt" Whitman (; May 31, 1819 - March 26, 1892) was an American poet, essayist, and journalist. A humanist, he was a part of the transition between transcendentalism and realism, incorporating both views in his works. Whitman is among the most influential poets in the American canon, often called the father of free verse.

Whitman claimed that after years of competing for "the usual rewards", he determined to become a poet. He first experimented with a variety of popular literary genres which appealed to the cultural tastes of the period. As early as 1850, he began writing what would become Leaves of Grass, a collection of poetry which he would continue editing and revising until his death. Whitman intended to write a distinctly American epic and used free verse with a cadence based on the Bible. At the end of June 1855, Whitman surprised his brothers with the already-printed first edition of Leaves of Grass. George "didn't think it worth reading". Whitman paid for the publication of the first edition of Leaves of Grass himself and had it printed at a local print shop during their breaks from commercial jobs. A total of 795 copies were printed. No name is given as author; instead, facing the title page was an engraved portrait done by Samuel Hollyer, but 500 lines into the body of the text he calls himself "Walt Whitman, an American, one of the roughs, a kosmos, disorderly, fleshly, and sensual, no sentimentalist, no stander above men or women or apart from them, no more modest than immodest". The inaugural volume of poetry was preceded by a prose preface of 827 lines. The succeeding untitled twelve poems totaled 2315 lines--1336 lines belonging to the first untitled poem, later called "Song of Myself". The book received its strongest praise from Ralph Waldo Emerson, who wrote a flattering five-page letter to Whitman and spoke highly of the book to friends. The first edition of Leaves of Grass was widely distributed and stirred up significant interest, in part due to Emerson's approval, but was occasionally criticized for the seemingly "obscene" nature of the poetry. Geologist John Peter Lesley wrote to Emerson, calling the book "trashy, profane & obscene" and the author "a pretentious ass". On July 11, 1855, a few days after Leaves of Grass was published, Whitman's father died at the age of 65. In the months following the first edition of Leaves of Grass, critical responses began focusing more on the potentially offensive sexual themes. Though the second edition was already printed and bound, the publisher almost did not release it. In the end, the edition went to retail, with 20 additional poems, in August 1856. Leaves of Grass was revised and re-released in 1860 again in 1867, and several more times throughout the remainder of Whitman's life. Several well-known writers admired the work enough to visit Whitman, including Amos Bronson Alcott and Henry David Thoreau. During the first publications of Leaves of Grass, Whitman had financial difficulties and was forced to work as a journalist again, specifically with Brooklyn's Daily Times starting in May 1857. As an editor, he oversaw the paper's contents, contributed book reviews, and wrote editorials. He left the job in 1859, though it is unclear whether he was fired or chose to leave. Whitman, who typically kept detailed notebooks and journals, left very little information about himself in the late 1850s.
