William J. Youden

William John Youden (April 12, 1900 March 31, 1971) was a statistician who formulated new statistical techniques in statistical analysis and in design of experiments. He developed the "Youden square", an incomplete block design developed from a 1937 paper, "Use of Incomplete Block Replications in Estimating Tobacco Mosaic Virus". He also helped to introduce the concept of restricted randomization, which he called constrained randomization.[1][2][3][4]

The award is presented each year at the Joint Statistical Meetings.[6]
