(b. Glasgow, 13 Sept. 1863; d. 20 Oct. 1935) British; Foreign Secretary 1929 – 31, chairman of Parliamentary Labour Party 1908 – 10, 1914 – 7, and 1931 – 2 The son of a cotton worker, Henderson started work in a steel foundry at the age of 12 after an elementary education. He gravitated from trade union activism to party politics, first as a Liberal and then with the Labour Representation Committee (later the Labour Party). He was a central figure in the latter's organization for over thirty years as general secretary (1912 – 35) and treasurer (1903 – 12 and 1929 – 35) of the party nationally and, in the Commons, as party chairman (1908 – 10, 1914 – 17, and 1931 – 2) and chief whip (1906 – 7, 1914, 1920 – 4, and 1925 – 7).
Henderson was an unlucky parliamentary candidate. He was first elected (for Barnard Castle) at a by-election in 1903, becoming only the third LRC member to enter the Commons, but he several times lost a seat at general elections and had to secure re-election at by-elections. His ministerial career was less important than his role as the architect of the party organization, but it was a distinguished one nevertheless. He joined H. H. Asquith's wartime coalition government in 1915, becoming the first Labour Party member to hold Cabinet office. Though nominally president of the Board of Education (later Paymaster-General) his real role was to advise on Labour issues.
When David Lloyd George became Prime Minister in 1916, he made Henderson Minister without Portfolio in his small War Cabinet. Henderson led a mission to keep post-revolutionary Russia in the war against Germany but was soon afterwards compelled to resign after urging Labour Party attendance at an international socialist conference without prime ministerial approval.
Henderson's next experience of office was as Home Secretary in the short-lived first Labour government (1924). Ramsay MacDonald (to whom Henderson had never been close) combined the foreign secretaryship — for which many thought Henderson best fitted — with the premiership, but Henderson played a prominent part in foreign affairs, attending the League of Nations Assembly at Geneva. In the second Labour government (1929 – 31) Henderson became Foreign Secretary. His main work was, again, at the League of Nations, where he was engaged in disarmament negotiations. Before these came to fruition, Henderson was in the forefront of the opposition to the cuts in unemployment benefit that precipitated the government's collapse. When MacDonald formed a national government, Henderson was elected party leader, but resigned after losing his seat at the 1931 general election.
Although soon back in the Commons, Henderson devoted most of the remainder of his life to League of Nations affairs. He presided over the World Conference on Disarmament and it was primarily for this work that he became, in 1934, one of only two serving or former British foreign secretaries to receive the Nobel Peace Prize.
