Peter Henry Andrews Sneath FRS, MD (17 November 1923 – September 9, 2011) was a microbiologist who co-founded the field of numerical taxonomy, together with Robert R. Sokal. Sneath and Sokal wrote Principles of Numerical Taxonomy, revised in 1973 as Numerical Taxonomy. Sneath reviewed the state of numerical taxonomy in 1995 and wrote some autobiographical notes in 2010. Webcoefficient and Sokal's distance coefficient is discussed briefly by Sokal and Sneath (1963:151) but only for coefficients based entirely on two-state characters. Since other types of characters are frequently used for matching coefficients, part of this paper consists of a description of the vari-ous scoring methods used for these charac-
