Kenneth Diplock, Baron Diplock
Born the son of an Irish solicitor, he attended Whitgift School and University College, Oxford, where he read chemistry and was later to become an Honorary Fellow. His father was Herbert Diplock and his mother was Christine Brooke.
As Lord Diplock, he chaired a commission set up in 1972 to consider legal measures against terrorism in Northern Ireland, which led to the establishment of the juryless Diplock courts with which his name is now associated.
At the time of his death, Lord Diplock was the longest serving Law Lord.
