PLAYFAIR, JOHN, an eminent natural philosopher and mathematician, was the eldest son of James Playfair, minister of Benvie, in Forfarshire, where he was born on the 10th of March, 1748.
In 1779, Playfair’s first scientific effort was given to the public, in "An Essay on the Arithmetic of Impossible Quantities," published in the sixty-eighth volume of the Philosophical Transactions.

There is a code called the Playfair cypher (named after the 1st Lord Playfair, 1818-98, who did not invent it, but embraced it).
This conventionally separates double letters with an intervening X. The cypher also relies on a key phrase which is used both for encryption and decryption at the other end.
The conventions of the Playfair cypher dictate that the encrypter constructs a five by five grid of the alphabet (treating J and I as the same letter), beginning with the key words and then mopping up the rest of the letters in the alphabet.
