Horst Feistel was a German-American cryptographer, born in 1915 and died in 1990, who worked on the design of ciphers at IBM and began the research that led to the Data Encryption Standard in the 1970s. The structure used in DES, now called a Feistel network, is commonly used in many block ciphers. Lucifer, one of the earliest civilian block ciphers, was developed by Feistel and his colleagues at IBM, and the Data Encryption Standard was based on an earlier design of his.
