This will be an unlikely HN entry, but as there was not pre-requirement, I thoroughly enjoyed a French book named "Peste et Cholera" by Patrick Deville, about Alexandre Yersin [1]. Yersin is mostly known for identified the bacillus responsible for the plague [2]. Not that it relates to our field, but the guy's dedication and hard-work was inspiring (similarly, Pasteur's life is quite interesting to read about).
Also out of our usual targets here, though somewhat more related, I enjoyed "Hard-Boiled Wonderland and the End of the World" [3] by Haruki Murakami. I found the universes interesting and enjoyed the setting of a world were programmers learn to compute and encrypt things in their brains (even if it's a small part of the story).
