Sara Teasdale (August 8, 1884January 29, 1933) was an American lyric poet.
 She was born Sarah Trevor Teasdale in St. Louis, Missouri, and used the name Sara Teasdale Filsinger after her marriage in 1914.

Unmuzzled OX was a quarterly of poetry, art and politics founded in 1971 by poet Michael Andre, edited in New York City and Kingston, Ontario.

 The circulation of "Unmuzzled OX" peaked at 25,000 in the 80s with "The Cantos (121-150) Ezra Pound."
 Regular contributors to "Unmuzzled OX" included Allen Ginsberg, Andy Warhol, John Cage, Daniel Berrigan, Eugene McCarthy, Margaret Atwood, Denise Levertov, Robert Peters, Robert Creeley and Gregory Corso.
 "OX" frequently features photographs of contributors by Gerard Malanga.
 Unmuzzled OX was located near the World Trade Center, and a translation by W. H. Auden of an opera by Carlo Goldoni appeared shortly before September 11, 2001.
 The publication ran until 2001, and most publications are still available.
Robert Louis Peters (October 20, 1924 – June 13, 2014) was an American poet, critic, scholar, playwright, editor, and actor born in an impoverished rural area of northern Wisconsin in 1924.
 He held a Ph.D in Victorian literature.
 His poetry career began in 1967 when his young son Richard died unexpectedly of spinal meningitis.
 The book commemorating this loss, "Songs for a Son", was selected by poet Denise Levertov to be published by W. W. Norton in 1967, and it still remains in print.
 "Songs for a Son" began a flood of poetry.
"What Were They Like?"
 is a poem by Denise Levertov written as a protest against the Vietnam War, envisaging a future where the "genocide" that the American bombing campaign began has been completed, and nothing is known of Vietnam or its culture.

Born in Iloilo, Philippines, Loewinsohn and his family relocated Los Angeles in the United States in 1945.
 They later lived in The Bronx and then settled in San Francisco, where he lived until 1967.
 Loewinsohn credits this proximity to North Beach with his own development as a poet: "I graduated from Abraham Lincoln High School in 1955, with the Beat generation happening all around me.
 I met all of the principals, heard Ginsberg, Snyder, Whalen and McClure read in Berkeley in April, 1956, and continued to write, mostly poetry, in that vernacular and (I thought) oracular mode."
 Loewinsohn then traveled, married in 1957, and worked as a lithographer for 12 years.
 In 1959, he published his first collection of poetry, "Watermelons" which contained an introduction by Allen Ginsberg and a prefatory letter by William Carlos Williams.
 He also co-edited the little magazine "Change" with Richard Brautigan.
 The poets who were most influential on his work included William Carlos Williams, Allen Ginsberg, Robert Duncan, Jack Spicer, Richard Brautigan, Philip Whalen, Gary Snyder, Charles Olson, Robert Creeley, Denise Levertov.
