Lawrence Monsanto Ferlinghetti (born March 24, 1919) is an American poet, painter, liberal activist, and the co-founder of City Lights Booksellers & Publishers.
 Author of poetry, translations, fiction, theatre, art criticism, and film narration, he is best known for "A Coney Island of the Mind" (1958), a collection of poems that has been translated into nine languages, with sales of more than one million copies.
Howl and Other Poems is a collection of poetry by Allen Ginsberg published November 1, 1956.
 It contains Ginsberg's most famous poem, "Howl", which is considered to be one of the principal works of the Beat Generation as well as "A Supermarket in California", "Transcription of Organ Music", "Sunflower Sutra", "America", "In the Baggage Room at Greyhound", and some of his earlier works.
 For printing the collection, the publisher Lawrence Ferlinghetti, another well-known poet, was arrested and charged with obscenity.
 On October 3, 1957, Judge Clayton W. Horn found Ferlinghetti not guilty of the obscenity charge, and 5,000 more copies of the text were printed to meet the public demand, which had risen in response to the publicity surrounding the trial.
 "Howl and Other Poems" contains two of the most well-known poems from the Beat Generation, "Howl" and "A Supermarket in California", which have been reprinted in other collections, including the "Norton Anthology of American Literature".
City Lights is an independent bookstore-publisher combination in San Francisco, California, that specializes in world literature, the arts, and progressive politics.
 It also houses the nonprofit City Lights Foundation, which publishes selected titles related to San Francisco culture.
 It was founded in 1953 by poet Lawrence Ferlinghetti and Peter D. Martin (who left two years later).
 Both the store and the publishers became widely known following the obscenity trial of Ferlinghetti for publishing Allen Ginsberg's influential collection "Howl and Other Poems" (City Lights, 1956).
 Nancy Peters started working there in 1971 and retired as executive director in 2007.
 In 2001, City Lights was made an official historic landmark.
 City Lights is located at 261 Columbus Avenue, on the nexus of North Beach and Chinatown in San Francisco.
George Whitman (December 12, 1913 – December 14, 2011) was the proprietor of the Shakespeare and Company, the celebrated English-language bookstore on Paris’s Left Bank.
 He was a contemporary of writers such as Allen Ginsberg, Anaïs Nin, and Lawrence Durrell, as well as a lifelong friend of the poet Lawrence Ferlinghetti.
A Coney Island of the Mind is a collection of poetry by Lawrence Ferlinghetti originally published in 1958.
 It contains some of Ferlinghetti's most famous poems, such as "I Am Waiting" and "Junkman's Obbligato", which were created for jazz accompaniment.
 There are approximately a million copies in print of "A Coney Island", and the book has been translated into over a dozen languages.
 It remains one of the best-selling and most popular books of poetry ever published.
 Because some of the material had been previously published, the first edition of "Coney Island" bears both a 1955 and a 1958 copyright.
Shigeyoshi "Shig" Murao (December 8, 1926 – October 18, 1999) is mainly remembered as the City Lights clerk who was arrested on June 3, 1957, for selling Allen Ginsberg's "Howl" to an undercover San Francisco police officer.
 In the trial that followed, Murao was charged with selling the book and Lawrence Ferlinghetti with publishing it.
 Murao and Ferlinghetti were exonerated and "Howl" was judged protected under the First Amendment, a decision that paved the way for the publication of Henry Miller, D.H. Lawrence, William Burroughs, and many other writers who offended puritanical elements of society.
Archie Randolph Ammons (February 18, 1926 – February 25, 2001) was an American poet who won the annual National Book Award for Poetry in 1973 and 1993.
Big Sur is a 1962 novel by Jack Kerouac.
 It recounts the events surrounding Kerouac's (here known by the name of his fictional alter-ego Jack Duluoz) three brief sojourns to a cabin in Bixby Canyon, Big Sur, owned by Kerouac's friend and Beat poet Lawrence Ferlinghetti.
 The novel departs from Kerouac's previous fictionalized autobiographical series in that the character Duluoz is shown as a popular, published author.
 The Subterraneans also mentions Kerouac's (Leo Percepied) status as an author, and in fact even mentions how some of the bohemians of New York are beginning to talk in slang derived from his writing.
 Kerouac's previous novels are restricted to depicting Kerouac's days as a bohemian traveller.
Lunch Poems is a book of poetry by Frank O'Hara published in 1964 by Lawrence Ferlinghetti’s City Lights, number 19 in their Pocket Poets series.
 The collection was commissioned by Ferlinghetti as early as 1959, but O'Hara delayed in completing it.
 Ferlinghetti would badger O'Hara with questions like, "How about lunch?
 I'm hungry."
 "Cooking", O'Hara would reply.
 O'Hara enlisted the help of Donald Allen who had published O'Hara's poems in "New American Poetry" in 1960.
 Allen says in his introduction to "The Collected Poems of Frank O’Hara", “Between 1960 and 1964 O’Hara and I worked intermittently at compiling "Lunch Poems", which in the end became a selection of work dating from 1953 to 1964.”
Christopher Felver (born October 1946) is a photographer and filmmaker who has published several books of photos of public figures, especially those in the arts, most notably those associated with beat literature.
 He has made numerous films (as director, cinematographer or producer), including a documentary on Lawrence Ferlinghetti, "Ferlinghetti: A Rebirth of Wonder", released in 2013.
