Arthur Balfour (1848–1930) first made his mark as a philosopher, publishing A Defence of Philosophic Doubt in 1879. He entered politics in 1874 and went on in 1902 to succeed his uncle, Lord Salisbury, as prime minister. However, he was unable to keep together a divided party and resigned in 1905. He served as First Lord of the Admiralty during the First World War, and as Foreign Secretary in 1917 he issued the Balfour Declaration, which was a step towards the foundation of modern Israel.
The Dutch artist Sir Lawrence Alma-Tadema moved to London in 1870, where he enjoyed enormous popularity and success. His portrait of Balfour has an atmosphere of quiet reflection, presenting his subject as a man of thought rather than political action.
