W. Edwards Deming 1900–93
American statistician and management theorist 

  1. In God we trust; all others must bring data.
    widely attributed to Deming, sometimes in the form ‘…all others bring data’. There is no evidence that Deming said this, but the association may have arisen from the saying ‘In God we trust; all others must use data’ being quoted without attribution in Mary Walton The Deming Management Method (1986)
