Re: Correction to popular myth about RSA
"Many important ideas in maths have been invented independently by multiple people. We try not to get hung up on who happened to be first, and sometimes the person it's named after isn't the first, but the one who did more with it, or was just lucky to be on this side of the Iron Curtain."
Is that really true? It might vary from field to field then. I think in pure mathematics it is important to establish priority, even if the results were obtained independently. Nowadays citations matter -- and determine promotions -- so if your original work is ignored over a later one, that has a negative impact on your career. For example, the journals of the London Mathematical Society (disclaimer: I'm on the editorial board) list one of the reasons for a corrigendum to be issued is to establish priority, even if the results are correct.
For instance, there is a famous lemma in permutation groups called Burnside's lemma, but it definitely isn't by him, and is often now called the Cauchy-Frobenius lemma. Both Cauchy and Frobenius are dead and already have enough named after them, but historical record is important. In most books since this became widely known, this fact is mentioned along with the result.
As a negative example however, the Cauchy--Riemann equations were known to d'Alembert, and Euler used them, about a century beforehand. This is mentioned on the Wikipedia page (I just checked) but not in Conway's GTM on complex analysis. (My other complex analysis textbooks are buried under a pile of things, and so I'm not going to check.)
Certainly 45 years after the fact, and now we know who the inventor of RSA is, things should be stated as "discovered by Cliff Cocks in the early 70s, and subsequently independently rediscovered by RSA". Certainly that is how I've been trying to do things in the book I've just finished writing, including both the Soviet and Western discoverers of results when they appear independent.
