William Blair (surgeon)
William Blair (28 January 1766 – 6 December 1822) was an English surgeon with an interest in ciphers and stenography. He was known also for contributing articles to ''Rees's Cyclopædia''. Biography William Blair was born in 1766 in Lavenham, Suffolk. He was the youngest son of William Blair, M.D., and his wife Ann Gideon. He qualified as a surgical practice in London under Mr. J. Pearson of Golden Square, who introduced him to the London Lock Hospital, and when a vacancy arose he was given a position as a surgeon to that charity. Blair was an M.A. but it is not known where he graduated.

Ciphers
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is ''encipherment''. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code (cryptography), code", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography. Codes generally substitute different length strings of characters in the output, while ciphers generally substitute the same number of characters as are input. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input. Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. For example, "UQJHSE" could be the code for "Pro ...
