Sir Kenneth Henry Clucas KCB FRSA (18 November 1921 – 27 August 2010) was an English civil servant.
He was mentioned in dispatches, which he insisted was not for any braveness against the enemy but for a "bold effort to sort out organisational weaknesses in the Signals Office.
However, his university life was cut short when he was successful in the Civil Service exam, which he sat for entry to the Administrative Class.
After serving as Principal Private Secretary to the Minister of Labour, from 1962 to 1966, he was head of the division responsible for legislation introducing widespread changes in industrial training.
He then served as Secretary of the National Board for Prices and Incomes (NBPI) from 1968 to 1970, an "extremely critical period" for the economic management.
