Ludwik Stanisław Dorn (pronounced as /pol/, 5 June 1954 – 7 April 2022)[1] was a Polish conservative politician, who served as Deputy Prime Minister and member of Sejm elected on 5 November 2007.
Dorn was born Ludwik Dornbaum,[2] to Polish-Jewish parents[3] Henryk Dornbaum (1910—1982), a socialist activist and Alina née Kugler (1915—2006), a doctor. All of his father's family was murdered during the Holocaust.[4]
In the 1960s Dornbaum family changed their name to Dorn. He was raised agnostic, but he converted to Roman Catholicism at the age of 51.[4] Dorn graduated with a degree in sociology from Warsaw University in 1978.[5]
From 31 October 2005 to 7 February 2007 he was Minister of Interior and Administration, resigned after conflict with the Prime Minister Jarosław Kaczyński.[6] Elected a Marshal of the Sejm on 27 April 2007, with 235 votes, after Marek Jurek's resignation.
On 4 November 2011, he, along with 15 other supporters of the dismissed PiS MEP Zbigniew Ziobro,[7] left Law and Justice on ideological grounds to form a breakaway group, United Poland.[8]
