David Trimble, Northern Irish lawyer and politician, 3rd First Minister of Northern Ireland, Nobel Prize laureate (died 2022)

William David Trimble, Baron Trimble, was a Northern Irish statesman and politician who was the inaugural First Minister of Northern Ireland from 1998 to 2002 and leader of the Ulster Unionist Party (UUP) from 1995 to 2005. He was also Member of Parliament (MP) for Upper Bann from 1990 to 2005 and Member of the Legislative Assembly (MLA) for Upper Bann from 1998 to 2007.

The First Minister and Deputy First Minister of Northern Ireland are the joint heads of government of Northern Ireland, leading the Northern Ireland Executive and with overall responsibility for the running of the Executive Office. Despite the titles of the two offices, the two positions have the same governmental power, resulting in a duumvirate; the deputy first minister is not subordinate to the first minister. Created under the terms of the 1998 Good Friday Agreement, both were initially nominated and appointed by members of the Northern Ireland Assembly on a joint ticket by a cross-community vote, under consociational principles. That process was changed following the 2006 St Andrews Agreement, such that the first minister now is nominated by the largest party overall, and the deputy first minister is nominated by the largest party from the next largest community block.

The Nobel Peace Prize is one of the five Nobel Prizes established by the will of Swedish industrialist, inventor, and armaments manufacturer Alfred Nobel, along with the prizes in Chemistry, Physics, Physiology or Medicine, and Literature. Since March 1901, it has been awarded annually to people who have "done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses." The Oxford Dictionary of Contemporary History describes it as "the most prestigious prize in the world."
