Tunny Tunny was a cryptographic machine used during World War II by the German Army. It was used for transmitting even higher-grade secrets than the Enigma and sometimes conatined messages from the megamurderer to his generals.(pg.150 codebreakers) The staff at Bletchley Park used the word Tunny in two ways: pg. 167 codebreakers This article will focus on the
 * 1) To describe the traffic on certain of the FISH links which radiated from the German High Command in Berlin out to the various Army Commands.
 * 2) It was the name of the equipment used to decipher the messages picked up from the FISH links.

Word War II

My project will focus on adding information in the section of W.T. Tutte wikipedia page that talks about Tutte's working during the work. As well as expanding the information available of some of his work in Graph Theory.  During WWII W.T. Tutte worked with the codebreaking group at Bletchley Park. His accomplishments while working with his team:
 * Breaking the German Army High Command's code that the British called FISH.
 * Tutte's work led to the development of the first working electronic computer, Colossus, to run decoding algorithm.



Contributions to Graph Theory Tutte authored many papers and a few books that include details on how he proved some theorems. Some of the topics that I plan to research in more depth are listed below:  References 1. S. Wylie, Breaking Tunny and the birth of Colossus, Action This Day (eds. M. Smith and R. Erskine), Bantam Press, London, 2001, pp. 317-341. 2. A theorem on planar graphs, ''Trans. Amer.Math. Soc.'' 82(1956)99-116  3. W T Tutte, Graph theory as I have known it (Oxford University Press, New York, 1998).
 * Generalization of the Hassler Whitney theorem on Hamiltonian circuits of triangulations for all planar graphs.
 * Expressed potential differences in an electrical networks as determinants using the Kirchhoff matrix.
