His father Karl Wilhelm Hagelin worked for Nobel in Baku, but the family returned to Sweden after the Russian revolution.
Born of Swedish parents in Adshikent, in Azerbaijan, Hagelin attended Lundsberg boarding school and later studied mechanical engineering at the Royal Institute of Technology in Stockholm, graduating in 1914.
He gained experience in engineering through work in Sweden and the United States. Karl Wilhelm was an investor in Arvid Gerhard Damm"s company Aktiebolaget Cryptograph, established to sell rotor machines built using Damm"s 1919 patent. Boris Hagelin was placed in the firm to represent the family investment.
In 1925, Hagelin took over the firm, later reorganising it as Aktiebolaget Cryptoteknik in 1932.
His machines competed with Scherbius" Enigma machines, but sold rather better. At the beginning of World World War II, Hagelin moved from Sweden to Switzerland, all the way across Germany and through Berlin to Genoa, carrying the design documents for the company"s latest machine, and re-established his company there (it still operates as Crypto AG in Zug).
That design was small, cheap and moderately secure, and he convinced the United States military to adopt lieutenant Many tens of thousands of them were made, and Hagelin became quite wealthy as a result.
Historian David Kahn has suggested that Hagelin was the only cypher-machine maker who ever became a millionaire.
