Is it by any chance 'Trachtenberg's High Speed Mathematics'?
It appears to me that if one wants to make progress in mathematics, one should study the masters and not the pupils. - Niels Henrik Abel.

Trachtenberg was an engineer who ended up captive in a concentration camp, where he thought about math to avoid going crazy, and I don't know his exact story of when he got out, but he did, and then taught the high speed mental math to others.
I had that book ganesh. There is a short biography at the beginning.

That's ironic, I normally go crazy thinking about math.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
