Richard Burdon Haldane, 1st Viscount Haldane, KT, OM, PC, FRS, FSA, FBA (/ˈhɔːldeɪn/; 30 July 1856 – 19 August 1928) was a British lawyer and philosopher and an influential Liberal and later Labour politician. He was Secretary of State for War between 1905 and 1912 during which time the "Haldane Reforms" of the British Army were implemented. As an intellectual he was fascinated with German thought. That led to his role in seeking detente with Germany in 1912 in the Haldane Mission. The mission was a failure and tensions with Berlin forced London to work more closely with Paris.
