@ Bruce,

He was a proponent of individual privacy.

Which tells me his time as a “cryptographer for the Navy” was not wasted.

It’s interesting to note just how many that have been involved with cryptography and are of a thoughtfull disposition are proponents for privacy.

@Clive – Or is just that those “of a thoughtful disposition” are proponents of privacy with or without a background in cryptography?

I would like to think thoughtfulness leads to supporting privacy.

Considering the election meddling brouhahas of the last couple of years, here’s something that Americans don’t hear so much about, this, also, from Justice Stevens, in dissent:

“If taken seriously,” Stevens wrote in his opinion, “our colleagues’ assumption that the identity of a speaker has no relevance to the Government’s ability to regulate political speech would lead to some remarkable conclusions. … It would appear to afford the same protection to multinational corporations controlled by foreigners as to individual Americans.”

I suspect that much more money was spent in this manner, on the 2016 U.S. election, than we’ll ever know . . .

That is very interesting!

Deep knowledge of math and rules of logic is very helpful and important in judge/Justice work in particular when parties try to move your decision making into emotional field or/and utilizing sophisticated tools as logical fallacies.

@ David

Very interesting.

One line that stuck out:

“…1941, having completed the Navy’s restricted correspondence course in cryptography, I went to the Great Lakes, Naval Station…”-stationhypo

ht tps://

Is this “correspondence course in cryptography” comprehisive or just cryptography 101 where more complete courses will be needed to code break?

@ crypto experts

In today vast world of cryptographic science is it possible to study crypotography via a correspondence course? Does anyone have an example of a cryptographic correspondendence course?

He worked in the naval SIGINT station at Pearl Harbor, doing the same sort of work as Bletchley Park. “Stanley Moe, Kimmy Lee, and I worked together around the clock for three or four days to break a new daily-changing call sign encyperment system”, plus traffic analysis. His unit worked on JN-25, but not Purple.
