Thomas Bayes, född cirka 1702 i London, död 17 april 1761 i Royal Tunbridge Wells, var en engelsk matematiker, statistiker och presbyteriansk präst. Han är mest känd för att ha beskrivit ett matematiskt samband som senare av Richard Price formulerades om till Bayes sats. Det publicerades 1764 som Essay towards solving a problem in the doctrine of chances i Philosophical Transactions of the Royal Society of London.

Portrait of an unknown 19th-century Presbyterian clergyman.

Identified as Thomas Bayes (d. 1761) in Terence O'Donnell, History of Life Insurance in Its Formative Years (Chicago: American Conservation Co:, 1936), p. 335 (caption "Rev. T. Bayes: Improver of the Columnar Method developed by Barrett.")

Again reprinted in Stephen M. Stigler, Springer Statistics Calendar 1981 (Springer-Verlag, New York, 1980).

A challenge "Who Is this gentleman? When and where was he born?" was published in IMS Bulletin, Vol. 17, No. 1, January/February 1988, page 49. The results were published in IMS Bulletin, Vol. 17 (1988), No. 3, pp. 276–278.[1]

David R. Bellhouse of University of Western Ontario in a reply argued that the man depicted being Thomas Bayes is unlikely, as

"The first thing to note in this picture is the apparent absence of a wig, or if a wig is present, it is definitely the wrong style for the period. [...] The second thing to note is that Bayes appears to be wearing a clerical gown like his father or a larger frock coat with a high collar [...] the gown is not in style for Bayes's generation and the frock coat with a large collar is definitely anachronistic. [...] For reference, I have used C. Willett Cunnington and P. Cunnington, Handbook of English Costume in the Eighteenth Century, pub. Faber & Faber, London, 1964."

Bellhouse compared pictures of other nonconformist ministers, that of Thomas Bayes' father Joshua Bayes (d. 1746), and that of Richard Price (1776).

Compare File:Philip Doddridge.jpg for the portrait of a nonconformist minister of Thomas Bayes' generation (dated 1751).

Stephen M. Stigler of University of Chicago, USA, wrote that it is possible that O'Donnell (1936) "got the picture from some (perhaps 19th century) source where it was identified as Bayes. The question would then be: 'What is that source, and what was that source’s source?' So little is said of Bayes in O’Donnell’s book that it is extremely implausible that he would choose him (and Thomas Simpson, who is also depicted in a similar style) as the subject for an invented picture."
