Horst Feistel (January 30, 1915
Life and work
Feistel was born in
MITRE corporation. In 1968, Feistel became a Research Staff Member at the IBM T.J Watson Center.[5] During his time there he received an award for his cryptographic work. In 1971, he patented the block cipher cryptographic system at IBM.[5] His research at IBM led to the development of the Lucifer and Data Encryption Standard (DES) ciphers. Feistel was one of the earliest non-government researchers to study the design and theory of block ciphers
.
Feistel lent his name to the
Feistel network
construction, a common method for constructing block ciphers (for example DES).
Feistel obtained a
Harvard, both in physics
. He married Leona (Gage) in 1945, with whom he had a daughter, Peggy.
