Andreas Figl
Army Colonel and Cryptologist

Andreas Figl (22 June 1873 - 11 November 1967) was an Austrian army officer 1 and autodidact cryptologist. He was the founder of the Austrian cipher bureau, as well as the country's code­breaking organisation. In 1926, whilst working for the Foreign Office, he wrote his book Systeme des Chiffrierens [I] (cipher systems). His second book Systeme des Dechiffrierens [II] (systems for deciphering) – a codebreaking guide – was probited by the authorities and was never published.

Born on 22 June 1873 in Vienna (Austria), Figl grew up in Vienna and Sarajevo (Yugoslavia). 2 He started an education as Army Cadet at the age of 14 and was promoted Lieutenant in 1891.

After a work-related accident in 1910, he retired as Army Captain (Hauptmann), but was recalled a year later to build new the cipher organisation of the Austrian Army. 3 Over the course of the next two decades he gained international recognition as a cryptographic expert. From 1920 until his official retirement in 1937, he worked for the Austrian Foreign Office (Außenministerium) [1].

In 1926, he produced Systeme des Chiffrierens (cipher systems), as a scientific publication of the criminalistic laboratory of the Vienna Police [I]. It contains 243 pages and 45 attachments, and is internationally recognised as one of the leading publications on classic cipher systems of the era.

It was his intention to produce another book a year later (1927) on the subject of code­breaking. It was called Systeme des Dechiffrierens (systems for deciphering), and comprised three parts [II], but the manuscript was confiscated by the authorities, and for any further crypto-related articles, Figl had to seek permission from the Austrian government first. It would be his last publication. Apparently the authorities did not want any code­breaking knowledge in the hands of the public.

Figl remained bitter about this decision, and kept secretly improving his manuscript. And even after his retirement, on 1 July 1937, he kept doing so. The last known addition was as late as 1953 [4]. In 1960, he became advisor to the newly established Bundesheer (Federal Army), but it was not until his 90th birthday, in 1963, that he was officially honoured for his work. Figl, the Altmeister of Austrian cryptography, died on 11 November 1967 in Salzburg (Austria), aged 94.
