Šnajder was born in 1948 in Zagreb, where he graduated in philosophy and English studies from the Faculty of Philosophy. He was co-founder and editor of the theatre journal Prolog as well as the editor of the editions published by Cekade. His short stories, essays and plays were published since 1966. From January to June 1993, he was a columnist in daily newspaper Glas Slavonije, Osijek, (Reader for the Melancholics), and, since January 1994 till 2013, in a daily newspaper Novi list, Rijeka, (Dangerous Connections). He is a member of the Advisory Board of the left-wing magazine Novi Plamen. His columns and his plays have supporters and opposers. Although Šnajder has been writing prose since ever, his first full-length novel Morendo was issued in 2012.
The very first professional production of Šnajder was his early play Minigolf – Drama Theatre Gavella, Zagreb, directed by Dino Radojević.
The Croatian National Theatre of Zagreb (HNK) has staged three of his plays, Kamov, smrtopis (Kamov, the Necrography) (1978), Držićev san (Dream of Držić) (1980), both produced by Ljubiša Ristić, and “Nevjesta od vjetra” (Bride of the Wind), staged by Ivica Boban. Kamov, smrtopis was staged in March 2003 by the Zagreb Youths' Theatre (ZKM) in the production of Branko Brezovec.
Dumanske tišine (Silences of a nun) is a play that was staged all over what was Yugoslavia. Another play of him, “Zmijin svlak” (The Snakeskin), about mass-rapings in Bosnian war, was played all over Europe, from Tübingen, Oslo, Warsaw, Kraków, Veroli near Rome (Festival Dionysia), Frankfurt/Main, Dublin, Wien, Kopenhagen, till Belgrade. This happens to be his mostly played text abroad, but not in Croatia.
But there is another play that seems to be much more controversial right from the date it was issued till today: Hrvatski Faust (Croatian Faust). There are certain similarities between debates in the context of Ralph Hochhut’s play “Stellvertreter” and this play of Šnajder. The opening night was in Split, 1982, directed by Dino Radojević. Very soon the play was staged in Varaždin (Petar Veček) and Belgrade (Slobodan Unkovski). But all the ideas to make it in Zagreb, where the events described in the play took place in 1942, under regime of ustaša (Croatian “quislings”), were made impossible from the very first moment. Actually, the play takes into consideration the history of the very theatre itself that in the seventies played two Šnajder's plays.
Šnajder’s Faust-play has something to do with what Germans call “Aufarbeitung der Geschichte” (workup of the history). Something like this is never an easy task, not for Germans, neither for many Croats.
“Croatian Faust” was the first Šnajder’s play of many that was played abroad: in 1987 Roberto Ciulli staged right this play in his Theater a.d. Ruhr. This production was shown everywhere in Germany, in several European countries, and in the USA (Chicago). SAT1 made a special movie-version.
The last production of Šnajder in relative normal circumstances used to be “Bauhaus” (ZKM, directed by Paolo Magelli, at the beginning of 1990). For the next decade Šnajder was excluded from any repertoire and theatre in his native town and land. At the end of 1999 Petar Veček staged Šnajder’s postsocialist grand-guignol “Kod Bijelog labuda” (At the White Swan), again in Varaždin. But Šnajder was played in Europe, because that sort of proscribed censorship could not work outside Croatia. Some productions in Europe, besides “Snakeskin”: “Hrvatski Faust” (Croatian Faust, Burgtheater, Wien, directed by Hans Hollmann), “Utjeha sjevernih mora” (Comfort of the Northern Seas in Frankfurt/Oder, directed by Michael Funke), “Nevjesta od vjetra” (Bride of the Wind, directed by film-maker Werner Schroeter). Miloš Lazin produced Šnajder’s play “Ines & Denise” in French, first in Sarajevo, then his theatre played this title in many French towns. French opening night took place in Villeneuve-les-Avignon in 1997.
A play about Josip Broz Tito, The Bones in Stone, was staged in March 2007 at the National Theatre of Bitola, Republic of Macedonia, directed by Branko Brezovec. In the year 2010 Kruna Tarle made his play written for puppets – Moja draga Tilla! ("My dear Tilla!”. Tilla stays here for the German actress Tilla Durieux who emigrated to Kingdom of Yugoslavia between the wars). That was a coproduction of Zagreb Puppet Theatre and Hfs Ernst Busch, German Academy for puppet-theatre from Berlin. German team made their own version, the opening nights took place in Leverkusen, after that in Berlin.
His most recent plays are: Enciklopedija izgubljenog vremena (Encyclopaedia of the Wasted Time, which is some sort of post-socialist Jedermann (Everyman), that is to say a sort of ‘transitional’ miracle-play), and Kako je Dunda spasila domovinu (How Dunda Managed to Save Her Country), based on motives of Maupassant.
Encyclopaedia of the Waisted Time was awarded by The Royal Theatre in Cetinje, Montenegro, 2009.
For more than eighteen years Šnajder has been writing weekly political columns, first in Glas Slavonije, daily newspaper issued in Osijek, Croatia, under the title “Početnica za melankolike” (Reader for Melancholics), further on in “Novi list”, issued in Rijeka. These are symbolically entitled Opasne veze (Les Liaisons dangereuses, after de Laclos). The selection covering the columns written until 1999 was published in the book Kardinalna greška (Cardinal Mistake), while the ones published from 1999 to mid-2004 are collected in another book - Umrijeti pod zvijezdom (To Die Under the Star).
Slobodan Šnajder is signatory of the Declaration on the Common Language of the Croats, Serbs, Bosniaks and Montenegrins within the project Languages and Nationalisms (Jezici i nacionalizmi). The declaration is against political separation of four Serbo-Croatian standard variants that leads to a series of negative social, cultural and political phenomena in which linguistic expression is enforced as a criterion of ethno-national affiliation and as a means of political loyalty in successor states of former Yugoslavia.
