Félix-Marie Delastelle (2 January 1840–2 April 1902) was a French cryptographer, best known for inventing the bifid cipher, first presented in the Revue du Génie civil in 1895 under the name of "cryptographie nouvelle". This cipher combines fractionation with transposition, and was an early cipher to implement the principles of confusion and diffusion. David Kahn described it as a "system of considerable importance in cryptology."
