Committee on Future Scientific Policy (the Barlow Committee) Blackett was one of the six members of this Committee, which produced the report 'Scientific Manpower' in April 1946. The Committee also produced a second report, never published, on proposed 'central government machinery for science'. See Bernard Lovell, 'P.M.S.
