Wilfred Banks Duncan Brown, Baron Brown PC MBE (29 November 1908 – 7 March 1985), was the chairman and the managing director of Glacier Metal Company (1939–1965), author of several books and articles on management and labour issues, university administrator, and United Kingdom's Minister of State at the Board of Trade (1965–1970).

Brown is perhaps best known for his collaboration with the organizational theorist Elliott Jaques on the Glacier Project, which Peter Drucker called "the most extensive study of actual worker behavior in large-scale industry".

Sponsored by Glacier Metal Company and its Works Council during Brown's leadership, the project ran from 1948 to 1965, resulting in the development or discovery of felt-fair pay, stratified systems theory, timespan of discretion, levels of work, product pricing analysis and career progression trajectories.

Brown later attempted to use these processes in governmental affairs as a member of the House of Lords.

He was appointed a Member of the Order of the British Empire (MBE) in the 1943 Birthday Honours[1] and made a life peer as Baron Brown, of Machrihanish, in the County of Argyll, on 22 December 1964.
