Boris Hagelin
Hagelin’s machines made cryptography deployable at organizational scale. Their history is central to understanding the practical tradeoffs among portability, key management, and mechanical security.
Boris Hagelin was a Swedish inventor and industrialist associated with a family of mechanical cipher machines used internationally. His company’s compact pin-and-lug devices included machines in the C-series and the U.S. M-209.
Machine cryptography at scale
Hagelin’s designs show how encryption moved from specialist rooms to transportable field equipment. Their use and later cryptanalytic study remain important to the history of mechanical communications security.
In memoriam
Hagelin died in 1983. His name remains closely associated with twentieth-century cipher-machine engineering.
