Arthur Henderson, Scottish-English politician, Secretary of State for Foreign Affairs, Nobel Prize laureate (born 1863)

Arthur Henderson was a British iron moulder and Labour politician. He was the first Labour cabinet minister, won the Nobel Peace Prize in 1934 and, uniquely, served three separate terms as Leader of the Labour Party in three different decades, and was elected to parliament in five by-elections in different constituencies. He was popular among his colleagues, who called him "Uncle Arthur" in acknowledgement of his integrity, his devotion to the cause and his imperturbability. He was a transitional figure whose policies were, at first, close to those of the Liberal Party. The trades unions rejected his emphasis on arbitration and conciliation, and thwarted his goal of unifying the Labour Party and the trade unions.

The secretary of state for foreign, commonwealth and development affairs, also known as the foreign secretary, is a secretary of state in the Government of the United Kingdom, with responsibility for the Foreign, Commonwealth and Development Office. The role is seen as one of the most senior ministers in the UK Government and is a Great Office of State. The incumbent is a member of the Cabinet of the United Kingdom and National Security Council, and reports directly to the prime minister.

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."
