Walter Tuchman

Walter Tuchman is a cryptologist and computer scientist who led the Data Encryption Standard (DES) development team at IBM in the mid-1970s. Tuchman and Carl Meyer were the primary developers of the algorithm, though there was a larger team that worked on its implementation. DES was adopted by the National Bureau of Standards (NBS) for commercial use in 1977. During the adoption process there was a great deal of debate over the involvement of the National Security Agency (NSA) in DES development as well as concerns over whether 56 bits were enough to ensure security.(1)
