		In 1939-40, Rowlett led the SIS effort that solved a more sophisticated Japanese diplomatic machine cipher, codenamed PURPLE by the U.S. Once, when asked what his greatest contribution to that effort had been, Rowlett said, "I was the one who believed it could be done."
		Rowlett also played a crucial role in protecting American communications during World War II, making fundamental and innovative contributions to the design of the SIGABA cipher machine.

	★ Reviews of books about Rowlett
		Rowlett was one of a small group of mathematicians who were introduced to cryptography by the legendary William Friedman.
		Rowlett was obviously acutely aware of the importance of protecting the technical information related to the activities he was engaged in ; however, in doing so he produced a document which although descriptive is not at all informative.
		Frank Rowlett's story is an intense day-by-day account of life as a cryptanalyst in the Signal Intelligence Service during the years leading up to WW II.

	Converter M-228 or SIGCUM
		The bump rotors meant that extra parts did have to be added to the machine to effect the conversion; it was not a simple case of rewiring.
		Even the early version of the machine appeared to be highly secure at first glance, which makes Frank Rowlett's feat of establishing its weaknesses impressive.
		The M-138 and M-138-A, indirect predecessors of the SIGABA, were rotor machines, of the Hebern type, acting upon the 26 letters of the alphabet, but with the motions of their five rotors controlled by a paper tape; in a way, these machines were the exact inverse or complement of SIGCUM.

		This means that they all belong to one class of the classes into which a program I wrote to count the number of interval method wirings for rotors of even size divided the possible wirings into.
		However, the actual wirings of two rotors for SIGCUM, a telecipher machine, which were recovered by Frank Rowlett during tests of its security have survived, and have recently been disclosed, and these rotors were not wired according to the interval method.
		Frank Rowlett then came up with what could be considered the core concept of the SIGABA: the idea of using rotors to control the rotors that enciphered text.

	Technical Intelligence Bulletins July - August 1998
		Frank Rowlett died Monday, 29 June, aged 90, of heart failure, at the Wilson Health Care Center in Gaithersburg, MD. "Rowlett supervised the half-dozen Army codebreakers who, after 18 months of effort, cracked the chief Japanese diplomatic cipher machine called PURPLE by US officials, in September, 1940.
		Rowlett appears as a notable figure in David Kahn's definitive work THE CODEBREAKERS (recently republished with an additional chapter to update developments since the first publication.) After WWII, Frank B Rowlett stayed in the field of cryptology, going to the National Security Agency.
		Since the end of the Cold War, it has been revealed the Frank Rowlett was a major contributor to the 'VENONA' decrypts, which revealed much about Soviet Espionage in the United States in late WWII and through the end of the 1940's.
