The Tin Drum (German: "Die Blechtrommel" ) is a 1959 novel by Günter Grass.
 The novel is the first book of Grass's "Danziger Trilogie " (Danzig Trilogy) and winner of the Nobel Prize in literature.
 It was adapted into a 1979 film, which won both the Palme d'Or, in the same year, and the Academy Award for Best Foreign Language Film the following year.
Allen Norton was an American poet and literary editor of the 1910s and 20s.
 He and his wife Louise Norton edited the little magazine "Rogue", published from March 1915 to December 1916.
 The periodical, partly financed by Walter Conrad Arensberg, served as an early showcase for the work of Arensberg himself, Wallace Stevens, Mina Loy, and Alfred Kreymborg.
 Norton's 1914 volume of verse, "Saloon Sonnets With Sunday Flutings", was published by Donald Evan's Claire Marie Press.
 Heavily influenced by fin-de-siècle aestheticism, Alice Corbin Henderson remarked that his work, along with the poetry of Evans himself, represented something of a revival of that style.
 Poems in the volume included "Impressions of Oscar Wilde", "Modern Love" and "Mrs. Eddy: a Mask".
Mina Loy (born Mina Gertrude Löwy; 27 December 1882 – 25 September 1966), was a British artist, writer, poet, playwright, novelist, futurist, feminist, designer of lamps, and bohemian.
 She was one of the last of the first generation modernists to achieve posthumous recognition.
 Her poetry was admired by T. S. Eliot, Ezra Pound, William Carlos Williams, Basil Bunting, Gertrude Stein, Francis Picabia and Yvor Winters, among others.
Günter Wilhelm Grass (] ; 16 October 1927 – 13 April 2015) was a German novelist, poet, playwright, illustrator, graphic artist, sculptor, and recipient of the 1999 Nobel Prize in Literature.

 He has won Sony Radio Awards for his play "Alpha" (2001) and for his script for "Different States" (1991), and a Silver Community Award for "Oxford Road" on BBC Radio Berkshire, as well the British Writers' Guild award for best dramatisation for his 1996 adaptation of "The Tin Drum" by Günter Grass.
 He was also part of the writing team for BBC Radio 4's "The Dark House", which won a BAFTA Interactive Award.
The Box (German: Die Box ) is a 2008 fictionalised autobiography by the German writer Günter Grass.
 It has the subtitle "Tales from the Darkroom" ("Dunkelkammergeschichten").
 In the narrative, the 80-year-old Grass' eight children, at their father's request, record conversations where they say what they think of him.
 "The Box" follows the writer's previous memoir book, "Peeling the Onion" from 2006, which ended in 1959 with the literary success of "The Tin Drum".
 It was followed by "Grimm's Words" in 2010.
Crabwalk, published in Germany in 2002 as Im Krebsgang, is a novel by Danzig-born German author Günter Grass.
 As in earlier works, Grass concerns himself with the effects of the past on the present; he interweaves various strands and combines fact and fiction.
 While the murder of Wilhelm Gustloff by David Frankfurter and the sinking of the ship the "Wilhelm Gustloff" are real events, the fictional members of the Pokriefke family bring these events into our own time.
The Meeting at Telgte (German: Das Treffen in Telgte ) is a 1979 novel by the West German writer Günter Grass.
 The narrative revolves around a fictional meeting for intellectuals hosted by Simon Dach after the Thirty Years' War.
 The story is an analogy for the post-World War II society in Germany, and of Group 47 in West Germany, of which Grass was a member.
