Chester Ittner Bliss (February 1, 1899 – March 14, 1979) was primarily a biologist, who is best known for his contributions to statistics. He was born in Springfield, Ohio in 1899 and died in 1979. He was the first secretary of the International Biometric Society.

Academic qualifications

Remarkably, his statistical knowledge was largely self-taught and developed according to the problems he wanted to solve (Cochran & Finney 1979). Nevertheless, in 1942 he was elected as a Fellow of the American Statistical Association.[1]

Major contributions

The idea of the probit function was published by Bliss in a 1934 article in Science on how to treat data such as the percentage of a pest killed by a pesticide.[2] Bliss proposed transforming the percentage killed into a "probability unit" (or "probit").

Arguably his most important contribution was the development, with Ronald Fisher, of an iterative approach to finding maximum likelihood estimates in the probit method of bioassay. Additional contributions in biological assay were work on the analysis of time-mortality data and of slope-ratio assays (Cochran & Finney 1979).

Bliss introduced the word rankit, meaning an expected normal order statistic.
