According to David Salsburg, in his small text _The Lady Tasting Tea: How Statistics Revolutionized Science in the Twentieth Century_ (W.H. Freeman & Co.) published in 2001, it is R.A. Fisher who is credited with the introduction of ANCOVA. The original paper can be found in "Studies in crop variation. IV. The experimental determination of the value of top dressings with cereals" published in Journal of Agricultural Science, vol. 17, 548-562. The paper was published in 1927.
