Peter Pain

Sir Peter Richard Pain (6 September 1913 – 16 January 2003) was a British High Court judge, who for many years specialised in labour law.

Born in Marlborough in Wiltshire, Pain's father was a solicitor. He was educated at Westminster School and Christ Church, Oxford, then became a barrister at Lincoln's Inn. In the early 1930s, he visited a Hitler Youth camp, and the experience convinced him that war was inevitable, and that he should oppose it by becoming a socialist. He joined the Labour Party, for which he stood unsuccessfully in the 1937 Farnham by-election.

Pain was rejected for military service in World War II due to his health, so he joined the Auxiliary Fire Service. He worked with John Horner for the right of auxiliary fire crew to join the Fire Brigades Union.
