Life and career 
The son of divorced parents (a public worker and a nurse), Gabriel was a high school teacher by profession before he went into politics.
On 15 December 1999, after the resignation of Gerhard Glogowski, who had succeeded Gerhard Schröder in office, Gabriel became Minister-President of Lower Saxony and served until 4 March 2003. After being voted out of office, he became the SPD's "Representative for Pop Culture and Pop Discourse" from 2003 to 2005, for which he was bestowed the nickname Siggi Pop. From 2005 to 2009 he was the Federal Minister for the Environment, Nature Conservation and Nuclear Safety in the first cabinet of Angela Merkel (CDU).
He has promoted the International Renewable Energy Agency. He called the speeches of Thilo Sarrazin, his party colleague who wrote critically about immigration, "verbal violence". Gabriel also once called Israel an "Apartheid-Regime".
Following the SPD's defeat in the federal election of 2009, Franz Müntefering resigned from the position of party chairman of the Social Democratic Party. Gabriel was nominated as his successor and was elected on 13 November 2009. He was re-elected as party chairman for a further two years at the SPD party conference in Berlin on 5 December 2011, receiving 91.6% of the vote.
Personal life 
Gabriel was married to Munise Demirel, with whom he has a daughter, but the couple divorced. He has been in a relationship with dentist Anke Stadler since 2008. They were married in a private ceremony in mid-August 2012, four months after their daughter Marie was born. Gabriel took parental leave, during the first months of the child's infancy.
