耶日·尼科德姆·科辛斯基（Jerzy Nikodem Kosiński），原名约瑟夫·莱温科普夫（Józef Lewinkopf），是一位波兰裔美国小说家，曾两度担任PEN美国分会主席，主要用英语写作。几十年来，科辛斯基以机智、伟大的说唱家和媒体名人而闻名。他的前三部小说大受欢迎。然而，1982 年 6 月 22 日，杰弗里·斯托克斯 （Geoffrey Stokes） 和艾略特·弗里蒙特-史密斯 （Eliot Fremont-Smith） 在《乡村之声》上发表的一篇文章“耶日·科辛斯基的污点”指责耶日·科辛斯基抄袭和不诚实。《画鸟》被广泛认为是自传体的;美国之声表明，这个关于犹太人大屠杀期间残酷童年的令人震惊的故事毕竟不是关于耶日，他在战争年代实际上过着相当舒适的生活。被改编为成功电影的《在那里》被证明是抄袭了一部早期的波兰小说。耶日·科辛斯基（Jerzy Kosinski）出演了两部故事片，几部纪录片和大量脱口秀节目。

他的父母摩西（Mojzesz）和Elzbieta（Liniecka）Lewinkopf都很富裕，足智多谋，有教养——尽管Elzbieta是一名业余音乐家，而不是她儿子所坚持的音乐会钢琴家，而Moses是一位精通语言的经理，但不是语言学教授。世俗化的犹太人莱温科普夫一家认识到纳粹对他们的祖国波兰的威胁，并于 1939 年底获得了将他们的姓氏改为 Kosinski 和父亲的名字改为 Mieczyslaw 的文件。科辛斯基是他们唯一的亲生孩子。

Jerzy Nikodem Kosiński , born Józef Lewinkopf, was a Polish-American novelist and two-time President of the American Chapter of P.E.N., who wrote primarily in English. For several decades, Kosinski was famous as a wit, a great raconteur, and a media celebrity. His first three novels were big hits. However, in June 22, 1982, "Jerzy Kosinski's Tainted Words," an article by Geoffrey Stokes and Eliot Fremont-Smith in The Village Voice, accused Jerzy Kosinski of plagiarism and dishonesty. 'The Painted Bird' was widely considered to be autobiographical; the Voice showed that this shocking tale about a brutalized childhood during the Jewish Holocaust was not after all about Jerzy, who actually lived rather comfortably during the war years. 'Being There', which was adapted as a successful film, was shown to have been plagiarized from an earlier Polish novel. Jerzy Kosinski appeared in two feature films a few documentaries and a large number of talk shows.

His parents, Moses (Mojzesz) and Elzbieta (Liniecka) Lewinkopf, were well off, resourceful and cultured—though Elzbieta was an amateur musician, not a concert pianist as her son maintained, and Moses was a manager skilled in languages but not a professor of linguistics. The Lewinkopfs, secularized Jews, recognized the Nazi threat to their native Poland, and in late 1939 they acquired papers changing their last name to Kosinski and the father's first name to Mieczyslaw. Kosinski was their only biological child.
